I sat down a Power Satellite Combinator and tried to remove it, I got an error when I removed it saying the following...

The mod Power Satellites (0.2.4) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event PowerSats::on_player_mined_entity (ID 69)
PowerSats/powersats.lua:270: attempt to index field '?' (a nil value)

PowerSats/control.lua:147: in function <PowerSats/control.lua:145>

I can't seem to replicate this issue. What other mods are you playing with? And could you upload your save to something like Google Drive so I can check it out?

i have the same error:

Die Mod Power Satellites (0.2.5) hat einen Fehler verursacht, der nicht behoben werden kann.
Bitte informiere den Autor der Mod über diesen Fehler.

I have a lot of active mods. (>300)
It's okay if this is too many to narrow down the problem.
All active mods are (as of today) up to date.

Launched satellites are also not recognized, whether this is a different problem or related to this one I do not know

Hey Siberwolf325! Thanks for your report and sorry for the delay!

While I had some issues running your save with all the mods (had to remove some of them), I think I've managed to pinpoint the issue and solve it. The power sats seemed to be still working fine, but the combinators didn't show the satellite count. I've managed to fix that, and while the ones that were already built and were broken won't start working, you should be able to remove them safely and rebuild them (or just undo the deconstruction) to make them work again.

Let me know if you encounter any more issues!
