Hi, thanks for your mod

After remembering that I did, in fact, install this, I thought about giving the underground a try. Placing the underground shaft froze my game for a solid minute, before stabilizing, which I assume was the whole underground map generating. Took me by surprise, but no big deal

The issue now is that wandering underground instantly tanks my UPS, making me drop to 50, with downwards spikes going as low as 35. I looked at my time usage, and modmash underground was indeed the culprit

I'm not entirely sure if it's because of the biters AI (I disabled them afterward, but that hasn't made things better, and I don't know if putting the limit on 0 after generating the underground would remove the existing ones) or if my massive modlist is responsible for it, but I'm just curious if this is expected behavior or not

Thanks again
