As i know this is a problem of all engineers:
Bots often don't fit through doors (exspecialy in those cave missions)
Can you please find a sloution for this ?
I have some ideas:
Shrink the bots
Make doors larger
Give us a bot warp nano
Give us a bot shrink nano
Give us a special "Indoor-Bot"
Those are the ideas i had (maybe there are some other (better, easyer do realize ideas from oher engis or metas and crats (don't know if they have such problems)
