Was building my 5th ion canon on 1 platform.
Total I placed 8.
Placed the 5th one while ship was in transit towards Vulcanus

Loaded autosave and built everything before flying towards Vulcanus and nothing went wrong.
So not sure but i guess its cause i build an Ion cannon while traveling that caused it

i haven't had time to play in peace (and find bugs) because of all the updates ;-)

to fix crashes i always need the error message from you.

I added a link in my main post of this thread, if that's not what you're looking for I won't be able to provide what you need.

I managed to recreate the bug more than once by constructing a radar for the orbital ion canon (Cannon and radar in platform hub) while space platform is in midflight between any two planets.

yes that's the right one. now i know where the error lies
BTW this is just text that you can copy, you don't need a screenshot ;-)
