I was one day accidentally afk (forgot the game on)
My computer was on the lock screen and when i opened it, I heard a strange sound (kinda like falling)
The game said I was killed by a zombie and wouldn't let me respawn even though i clicked the restart button. When the game didn't let me respawn i tried to close the game. The game wouldn't close. I Had to close the game from the Task Manager.
When I got back into my world, it seemed normal until i tried to use my smelting system.
In the Smelting system there are droppers that drop the smelted items. Now for some reason the redstone clock was broken. I replaced the redstone clock with a new redstone clock but now for some reason the droppers are broken and will not drop any items
I tried if other droppers work and it was only the 2 in my smelting system. I tried replacing the droppers but they still wouldn't work.
Firstly, modded games are not supported here.
That being said, it's likely this issue isn't directly related to the use of optifine. However, since the game was forced closed through the task manager, there is no way for the game to ensure that game data is properly saved before quitting. This can result in many problems, the least of which could be a broken redstone circuit. There isn't really a way around this, so this ticket is being resolved as invalid.
