I have a crossplay account, but the forum will not let me start a topic on the nintendo switch bug side; consider that it's own bug to be reported.
When I am in sanctum anatomica and the new whispers' tilesets the fan will not kick on while docked. The colors go wonky neon and invert as if the switch is overheating. When I take the switch off the dock, the fans kick on full throttle and cool the system down and the colors will go back to normal. As soon as I dock the switch again, the fan will idle. This only happens in the sanctum anatomica and the whisper's tileset. No other area is affected, and it only happens while playing docked.
