I can link you the save even tho i don't know if it is linked to it. Just try to open a bot part box at the cargo bay or open lab management, will directly send an error.. (using v1.30.15b)No botlab error error has been reported on 1.30 which is out on patreon for a long while.
That being said I'm always looking to find hidden issues.
If a bug is reproducable and you use an unmodded game I am interested to have a look at the save (with info how to provoke the error). Just PM the save to me.
Thanks.
(i tried installing a mod at the very begining but realised it was out of date so reinstalled the game and started a new save so there shouldn't be an issue but maybe it is the reason and i missed something)
