Hot CPU without any reason

[Fruitloops]

To my dismay I had to realize that my cpu after a few minutes on the server to 100% load is running, and it starts jerking, although nothing to jerk is there. and after I stop the game and stop the launcher and no program is running anymore, the cpu stays at 100 percent working. 5 minutes later started taskmangager and saw, the cpu is still running on 100 % only a newstart of computer helped, and i tried another discovery mod, and my cpu running on 5% as usual. so what the..... is wrong with the actually mod version? i am sure i am not the only player with hot cpu, and i dont wana risk my cpu burning through.
