I have a current issue with my server that is not affected due to hardware performance. Currently I am running a 1.14.4 server with the Create mod (It would not let me select 1.14 in the affected versions menu). The server has been running perfectly fine for the past couple months, lately it has been lagging and occasionally crashing. The in-game performance seems fine for the most part, placing blocks and removing them seems fine. The issue lies with mobs mostly, they seem to glitch as they move. Eating food also tends to be laggy and takes an extra second or two in order for the action to be executed as well as things like opening doors. Thank you.
