So my experience with this one Eggmine in TR_Mainland is a bit too frustrating and also some noticable issues.

One noticeable bug I encountered is there are some Kwama Eggs floating in mid-air. Found a bunch of these in the Queen's lair.

The other issues I found is that the overall place is too difficult if not impossible to traverse.

There's paths that are either nearly blocked off by things in the way like a stalactite or large pile of dirt. Or pathways far too narrow that its impossible for the play character to fit into. I was playing a male Nord but I don't think any race the player is using would fit inside. And one path that's too steep to climb without the aid of leviatation or high acrobatics and I don't think it was meant to be like that especially for an eggmine.

I've provided the screenshots below:

Stalactite in the way (you can squeeze through but I feel its too in the way for its own good)

Too steep incline to reach the upper pathway, you can use leviatation or just have a high acrobatics, but I think its still too steep that it doesn't make sense.

Extremely narrow pathway that its impossible to enter without togglecollision
