Hello,
i noticed that the bots take on a canister and try to extinguish the fire, but it seems they only try once and then switch to rebuilding/repair even if the fire will still burning and there are plenty of water canisters.
so in the end the repair is in vain and the fire spreads still while damaging the bots which try to repair ....
--> the bots should have a priority job of extenguishing the fire, at least when there are water canisters available.....
that happend from my personal roboport because on this location i did not have any roboports, aside from no water canisters
