Hello,

As we know, spores are absorbed by egg rafts, big and small. Small egg rafts are supposedly capable of spawning enemies, but only wriggler types.

Under the pollution tab, you can see where the spores went (referred to as pollution). If a chunk has pollution on it, an egg raft will absorb it.

The rules for small egg rafts appear to be different: Small concentration of spores is completely ignored, and High concentration is absorbed, but categorized as "Damage to trees" (unlike other rafts that are reported correctly as rafts)

Not only that, Small egg rafts seem to never spawn wrigglers, due to their inability to absorb spores correctly. The spores should easily cover the cost, but enemies never come out

Small rafts don't absorb pollution viewtopic.php?t=124680

OK, then why not say so? And why do they say they spawn wriglers if they don't absorb the spores? And what's with the damage to trees thing?

"Damage to trees" is trees absorbing pollution by being a tree and getting damaged in the process.

They spawn wrigglers in defense. Nests and rafts don't absorb pollution to spawn enemies, they absorb pollution to send enemies to join an attack party. Wrigglers from small rafts can't join attack parties because the small rafts don't absorb pollution. As I understand it this change was to avoid the weird gameplay where it was optimal to kill regular rafts and leave the small rafts untouched so you'd never get stomper or strafer attacks.
