Nerf Room Destabalization

I love how I can collect a stack of 60 crystals from just running maps, but I cant put together a good temple run with those 10 rounds of tile sets because everything just disappears after one run. So everything is always tier 1 or 2. At this point I would love to just make a single Temple run that just converts all your crystals into tiles and then they destabilizes the entire thing after the run. You can balance around knowing that there is an inevitable cap to the number of tiles in a Temple run. I sometimes forget that I have capped out on my crystals because its so damned unsatisfying watching everything disappear before it ever gets built up that I skip the entire process. There's some cool loot available there, sure. The entire process is like washing my car in the frigid cold while wearing swimtrunks. Feels like I don't really need to do it, and it's the most miserable way to be doing it.
