Turn 9 floor missing

Starting last week, I have an issue in the second coil turn 4. The floor for phase one (blue with glowing markings) is missing on my screen and I start the fight with the graphics from later phases (rocky floor with no markings).

Since most groups use the markings for their strategy (meteor placement, golem kiting) I would like to find a way to get my phase one floor back.
Maybe it is an issue with my software files? If so, is there a repair file for the game?


(I am a noob when it comes to the forum search, so if I missed an exsisting post on this matter, I apologize!)

I believe there is a repair function on the launcher options, if I recall correctly! ^^
