I know this will be very difficult to reproduce, so I'm wondering if it happens more often or i hit a very rare bug

upgraded a save from 1.1.107 to 2.0.10, played for about 4 minutes and spidertron I was in completely disappeared without a trace. Nothing in log at the time it happened.

when I loaded the save again and did more or less the same actions, it didn't happen again (tried for 15+ minutes)

Could it be the issue where they take damage from their own explosive rockets and it died?

definitely not, there were no rockets equipped

[Version 2.0.15]

I'd like to add that they disappear when not driven, too. I could not reproduce it by roughly retracing my steps.

I am on Gleba and using the spidertron remote to control a grouped pair on Nauvis. I had them zigzagging through two biter bases and was watching them. Health and shields were maxed or near max. One construction robot was trying to catch up with the pair.

I completed researching "Epic quality" and swapped to the research queue to reorder it to start another level of "Stronger explosives". The tech screen pauses the game.

When switching back to the field[1], the spidertrons were gone. There was no destroyed icon flashing (even though this wouldn't be possible seeing full health/shields and the game paused during tech). The lone robot started flying back to the base. The spidertron controller which had a (2) on it, now had no numbers listed.

[1] I don't know if I hit ESC too many times, bounced the view Gleba and then clicked back to Nauvis, or if I went straight back to the Nauvis view.

Post a save and exact steps that let you reproduce this please, see 3638.

Both I and the OP could not reproduce it. The save is long gone in my case.

Did you maybe press ctrl + z and undo placement of the spider causing it to be deconstructed?

For myself, no. These spidertrons were placed a long while ago. Hours and hours worth of undos ahead of them if the queue was even that deep.

Im my case also no ctrl-z, the spidertron was already placed in the save long time ago. I can provide the save pre-conversion (sadly autosave ticked after the disappear happened so i had nothing on between), but as i said, i didn't manage to reproduce it.

I just verified and i was sitting in the spidertron in the save already, if that matters anyhow. But another attempt also didn't reproduce it either.
