Thanks for an interesting mod! I have a map that reliably kills the Factorio session, and I can't make any further progress on my game. Any idea what the problem is?

Error while running event Factorio-Tiberium::on_tick (ID 0)
LuaEntity API call when LuaEntity was invalid.

That... is an interesting error.

Do either of the following commands fix it? Assuming you can load in long enough to get them in

/tibRebuildNodeAndDrillLists

/tibFixBrokenThings

Neither fixed it. I had to patch control.lua to do an entity validity check for each item found in the loop at l.117:

  local entitiesToDamage = surface.find_entities(area)
  for i = 1, #entitiesToDamage, 1 do
    local ent = entitiesToDamage[i]
    if ent.valid 
       and (global.exemptDamageItems[ent.type] == nil)
       and (ent.prototype.max_health > 0) then
       ent.damage(global.structureDamage, game.forces.neutral, "tiberium")
    end
  end

I have some weird stuff going on in my game (e.g. power poles get damaged even though they're supposed to be immune).

Huh, okay. I'll need to include that, and let the growth coder know. Maybe I should be rebuilding the list or something every so often...

Power poles should have been fixed... which ones? All? Just medium?

I find both small and medium power poles being damaged. Belts are being correctly protected.

Poles being damaged should be fixed, again.

The main discussion error fix is also implemented.
