hmm strange bug, dying restarts the current level, sorry about that. Definitely interested to know if you recreate it, I tried but nothing so far :/
I tried playing through again and while it didn't happen immediately, after a few times of picking up wrench and fire extinguisher it happened again.
Haven't found what the exact needed sequence of events is, if there is some timing to it or something. Will test again later and see if I can recreate it again
After playing about just picking up each of the times, throwing the wrench around and flying into the wrench while using the fire extinguisher, it picked up the wrench but didn't drop the extinguisher.
No errors were printer into the console, still haven't found a reliable reproduction unfortunately
After a bit more picking up and dropping of items, it happened with the bucket and wrench too
