Invisible textures

Game version: 1.8.0-71665-194
Type of issue: Bug
Mods: No

Bug Description:

I’am was completing the first level with my own tactic (just using dash (shift button) and sword attack at every beat) and soon was discover, that a lot of textures of walls and floors just disappear, became invisible, which made me to fall into abyss, because i just cannot see where the cliff ends. But after falling into it i was respawned not on the same arena, but on the one of previous arenas, and i just cannot came back on current arena because of this grey barriers at arenas exits, so i just stuck there and cant go next.

Steps to Reproduce:

Step 1
Start the level Voke (Maybe it can be any level at the game)
Step 2
Try to complete it using dash (shift button) and sword attack at every beat
Step 3
Look out if any of wall/floor texture is invisible but you still can walk at them and crash into them.
