I use the mod robo army https://mods.factorio.com/mod/robotarmy, it's fun but the dev is busy with real life so no way to fix the issues.

the issue being that due to the HP regen of the units, combined with the "burning" (fire acid?) the bots get paralised because they are "attacked" but actually no one is left. Result, hours later, when i have a massive base, tons of robots and the bitters, the robots i need to remove because, they destroy all the enemies, ok, but, due to this burning incidend, my UPS/FPS goes down to 3 - 4 out of 100, and i have tons of PC ram and more.

Also, even without the robo army mod, it's extremly annoying that bots constantly fly around, almost randombly, to replair because constant 1 damage.

I don't get, why does this mod need to add this burning thing? it's a small damage, that makes no real impact, except for the UPS/FPS.
