Invisible Pathways

Title: Invisible walkways

Summary: bug were some walkways just turn invisible for no reasons whatsoever and you cant interact at all with the ground where it was.

Steps to reproduce:
i have yet to find out how to reproduce it but it has happened in different games about 3 times now and at the moment its only with the rayaas children the darkest red colored path. i think it has something to do with the number of hearthlings because it only happens after awhile of playing

Expected Results:

Actual Results:

Notes: it seems that quitting to main menu then loading the game fixes it.

In my non Rayya game, two blocks of this particular path disappeared as well. However I fixed it :
I created a new path around it, then I erased the block I didn’t want and launched the construction. My two blocks were finally here.
