Yes.. idid it all of this and played only in official vanilla server....
But i don't saw this problems again in my last play... so could be somehitng with my connection causing desync, i think...i don't know...

sorry for delay, but i do not receive notifications and to busy as well..

Actualy i saw that is not just deagle.. i not try all, but even shotguns i have de same problem in that time. I don't have time to test more after...
