Cool!

I tested the bug a few more times (in the interest of reproducing the error, of course...) and got 2 more spider queens and a King Serpent, after which I overcame temptation and uninstalled the mod. But I'll be glad to put it back now.

Yes, there was a bug, thanks for spotting it! Should be fixed now.

So, whilst I like this mod a whole lot, I recently experienced some weirdness that almost has to be cause by this.

I was using the tier 1 Druid "summon animal" spell, on the surface, on arctic fertile plains, and got a Dread Spider Queen. Which the tier 1 spell obviously shouldn't be able to summon.

If it matters, I was summoning into a stack that already contained another Dread Spider Queen that I'd evolved up from a baby.

Is there any way your mod could be causing this?

very smart and intuitive addition, the devs should consider including this into the main game ^^

Yeah, it does conflict. My mod uses standard random animal summon spells and 'Summon Spell Tweaks' removes them.

I take it your mod conflict with:
