When on a server (It doesn't matter which one) an arsenal is used repeatedly, to equip and remove things, over time it generates lag (Visibly in the movement, VOIP and GM camera if it exists) that does not disappear until that arsenal is removed, otherwise it ends up causing a general server crash. The lag its not only generated with the spamming, its generated overtime by normal use of it.

Tested with about 25 people playing co-op in different game modes (Vanilla and non-vanilla).
