If More Quality Scaling is installed alongside this mod, then all panels above Normal quality no longer receive any sunlight as input. If the scaling options for Heatpipes and Reactors are disabled they work fine, though.

Hm. I looked into it, and it appears that the More Quality Scaling mod relies on a common workaround that automatically creates separate entities with ID-prefixes for each quality tier and then assigns new, scaled properties to each of them. A higher tier entity, when placed down, is immediately replaced with the appropriate mod entity through a script (this has to be done in reverse when mining it). Before that, the mod searches for particular entities (like those that use the reactor prototype, which the thermal panels do) and uses those as a base. So the mod affects the thermal panels (entities clearly outside of its intended scope) by accident and also breaks them. This is because the modded higher tier variants can't be recognized by their ID's and therefore won't have the heat-generating script applied to them. What's more, mining the higher tier panels returns them with only a fraction of their health (just 40% in the case of the legendary tier).

I'll see if there is anything I can reasonably do on my end, but you may want to write to the author of the other mod as well.

Thank you for the swift reply. I ended up disabling the reactor scaling (which killed a lot of my planets), so it's fine now. I'll see if I can get around to messaging the author of More Quality Scaling in the near future to see if they can do anything about it.

All right. I am sort of interested in increasing my mod's robustness towards changes made by quality-related mods, so I am at least looking into the issue.

Just a small update: I found out that the issue with health lost on entity mined stems from an option in Creative Mod that is supposed to restore health to 100%. But it always sets health at the level of the normal quality tier. I have reported this to the author.

Yeah, makes sense that it's from a different mod. I didn't actually have this issue, so I was a bit confused

Right!

By the way, I have just reported the issue to the author of More Quality Scaling. See this thread.

Thanks for taking care of that! I might've gotten around to it eventually, but it's probably better that it's taken care of immediately.

No problem!

Hi again. I have just uploaded v2.1.18 in which the issue has been resolved! The heat generating script now applies to the clones from More Quality Scaling, and with correct output as well. (Certain things were made easier by recent changes made on their end.) Take a look at the changelog. Keep in mind that entities will disappear, if the relevant setting is disabled, or the mod is uninstalled, but you may have already noticed that.

By the way, how exactly were a lot of your planets "killed" in connection to reactor scaling? Curious about what the problem was.

Heyo,
Glad to hear that all the issues were resolved.
Regarding you question:
I had disabled the scaling options for reactors and heatpipes in More Quality Scaling, which lead to all my quality nuclear reactors, heating towers and heat pipes getting deleted. This ended up with me losing power on Nauvis (Nuclear Reactor - Luckily steam buffer kept it alive long enough for me to get back), Cerys (A large portion of the heat pipes there were quality as well as one heating tower that I had built), Paracelsin (Both the nuclear reactor and all the heating towers from Cerys), Aqulio (Luckily just the reactor), my main Space Platform (nuclear reactor - also steam buffer and I had a spare reactor on my ship), Gleba (Heating tower), Frozeta and Nix (Metal & Stars).
I was luckily able to fix all the relevant planets without many issues, but it was certainly a pain.
Also: Holy wall of text, lol

Ah, so it was entity deletion upon changing that setting. Yeah, that is rough! sh4dow did explain that it's an issue that is difficult to fix.

Anyway, the mods now work together as intended, so I'll mark this issue as resolved.
