So the link detector works whenever it detects the platform then emits a redstone signal afterward right? So by placing a TNT block on a link detector block and it detects that the platform has reached a certain floor; the game crashes. After booting the game again, however, the TNTs I placed is now exploding, and I found out that Minecraft is now unplayable as before the bug happened, I have around 220 FPS and after it crashed, it dropped into 10 with 18 FPS at max. The FPS didn't get back to around 220 FPS without deleting that world and booting the game again.

Please send the crash log.

I would reproduce the bug and send the crash log later as I'm still in my classes 😂
