Hello guys!

So, I like to play modded survival, but I am having this weird problem, and its confusing.

So, I was playing and suddenly, lots of mobs spawned and for some reason, my Minecraft crashed (I think because of too much RAM usage), so I restart Minecraft, and then the troll starts, whenever I would jump, I would jump continuously non-stop, until I go to a certain GUI (Pause, Inventory, Command, or any other mod GUI) it would stop. These are the mods I am currently using:

I tried changing keyboards but still it happens, what is wrong?

Thank you for your support!

EDIT: Fixed the problem, it's Optifine D3, when I downgraded it to D2, it became normal

Sometimes it jams the space bar (or any button) just double tap it and it should fix it.

It still happens, but thanks for the suggestion though (I almost broke my keyboard from raging about this)
