Misc. Robots (https://steamcommunity.com/sharedfiles/filedetails/?id=724602224) adds worker bots that are not colony pawns, but are controllable by the player.
Misc. Robots WorkTab Support (https://steamcommunity.com/sharedfiles/filedetails/?id=2271338001) allows the player to specifically control which WorkTypes these robots can do.
These robots are not any guests, but the PawnColumnWorker_Guest column throws a null reference since pawn?.guest is null.
Can we add a null check on the guest variable inside GetIconFor and GetIconTip for a null guest reference?
Thanks,
