I am using this mod, along with Alien Biomes, and it seems that the Trees from Alien Biomes don't give a larva, as it says they should be given at a 10% chance.
i have harvested more than enough trees that the random chance should have been hit by now.

i just found a larva in my inventory without getting a popup on harvesting a tree, i guess?

Hello. Yes, there could be a problem with it because when you harvest the tree is checks that entity type starts with "tree-", which covers trees on a starting planet in vanilla playthrough. I will think about adding another 10% chance of getting two larva instead one when you turn Bee Queen into Worker Bees in the incubator shortly and push an update.

Thanks for interest to this mod =)

Larva is added silently into your inventory when it hits that 10%. Probably I need to print some message in chat when it happens

Hey, just dropped an update.
1) I added clear message when larva find event triggers so you know clearly when it is been added into your inventory
2) I already made 2% chance of getting extra larva when turning Queen into Worker Bees in the Incubator just didn't mention it in the lavra's description. Fixed it also

You are a legend, absolutely amazing!
