I released add-new-Cell mod and received comments from users. it's black void.
One user reported me first time dungeon show void, but after loading auto-save dungeon`s graphic appear.
Similarly, arrows can't fire and immediately drop on floor untill quicksave&load.
I tried checking it on my PC using upload file in ver1.6.89.0 Vanilla environment, but can`t get reproducibility.
Any advice would be sincerely appreciated.
