Not noticed when the right pipes of warp gate get removed (left are still there), I regognized it while rebuilding top platform.
Warp gate 3 research was the last research, vulcanus (2x jumps right after research) and fulgora (no jumps) research was befor.
Every time when I drop the gate I get an error, see below.

Unfortunatly warping or game restart did not help and all autosaves missing this pipes...
Playing without warp gate sems not much fun, so i hope a bugfix can rescue my run or at least avoid future pain for other players ;)

Quick response: use the command "/dw_reset_warp_platform" (there's also one for harvester, just in case /dw_...)

Longer response: i've checked your save and mods, it doesn't seem like you have any mod that would explain that (especially as these entities are indestructible / not minable).
Depending on which version you started with, there was a "bug" involving the harvesters that could level up and overlap with these entities and remove them, which as been prevented in later version (and as I didn't find the pipes in your harvesters, i'm not sure it's related).

Did you use editor mode at some point ? Or another mod that could change some entities ?
In any case, if you happen to reproduce it, i'd be interested to see how, to fix it.

I'm happy, the command worked. Thank you!

I updated your mod once cause changelog looked as it would mean no harm to the save.
No, I use rarely the editor, and not in this run.

At start I had also AAI Loader and Mining Drones active, but removed it later.
There was no real issue with them, but AAI Loader where way more expensive than your loaders and Mining Drones have their own productivity update which stacks with nothing else.

Sure, if it happens again I will let you know.
By the way, awesome work! You give me much hours fun with this mod :)

thanks :)
