That's really strange, I tried to replicate the bug but no way :/ you're playing on PC ?
yep. also tried it again and it didn't seem to happen? might try again in a moment, iirc when it did happen I was placing it on the edge of the river in the water, and when it did work it wasn't in the water...
will definitely check again, maybe I just got unlucky?
Edit: tried to replicate it several times, no luck. very odd. however, I did notice that when I hit E to build something, the game would often freeze for a second. no idea if that would be connected or not
Oh that freeze is still an ongoing feature. When buildings or big objects are added to the map, the navigation stuff is updated and sometimes a little freeze can occur. That's annoying but I'm still trying to improve this part, it's kinda important to allow the characters to walk anywhere they want or just being able to wander in a new house without being stuck in front of a staircase X)
But about the previous problem I'll keep searching, maybe I'll find out what happen ! Thank you for your feedback it's really cool !
