Possible solution to the problems of terrain formation in trial of the Sekhemas

I want to clarify that this is just a guess.
I noticed that after each weapon change, the number of minions you actually have is added to the number of your minions in the upper-left corner. Thus, by the end of the floor, you can see a number close to a hundred, but in fact you have as many minions as you should have (in my case, eleven). You can see it in the screenshot. If you exit the trials and go back in, the counter in the corner will reset to the actual value. So I've gone through more than ten trials, re-entering the last room of the floor and resetting the false minion counter, and still haven't found this error (previously, this error occurred about every third playthrough). If you also encounter this error, try this solution, I will be grateful for the feedback. I hope that the information provided will help fix this bug.
