When a factissmo building is destroyed with this mod enabled, the game crashes.

Error while running event factorissimo-2-notnotmelon :: on_entity_died (ID 4)
factorissimo-2-notnotmelon /script/factory-buildings.lua:577: Failed to
generate factory item. Are you using the quantum-fabricator mod? See

This is due to factorissmo tries to spawn a factory item and mark it for destruction. But this mod detects a item is marked for destruction, and calls instant deforestation on the item, delete it before factorissmo asserts the item is valid.

Solution: check for factory item and don't delete it.

In scripts/debuilder.lua, in instant_deforestation(entity, player_index), line 130:
if Non_deconstructable_entities[entity.stack.name] then return end

(ps, you have no idea how long I spend trying to figure out what was going on XD)

Also, I can't remember if I updated this part or if this was on last update, but Non_deconstructable_entites need to contain 6 entities, since there are total of 6 possible factory buildings.
["factory-1"] = true,
["factory-2"] = true,
["factory-3"] = true,
["factory-1-instantiated"] = true,
["factory-2-instantiated"] = true,
["factory-3-instantiated"] = true,

ngl, I'm kinda mad that instead of like trying to notify me of the crash that was known for more than month notnotmelon just added a warning to their mod and marked the issue as resolved. What was resolved about it?

Anyway, thanks for debugging it, fixed.
