I might have found a cause for that Object 2:1029 not found rpt spam.
See netID of the UniformContainer in the debug console in the screenshot (Unit was spawned and geared serverside (Not sure if it matters for the repro)).
After sever exec of this code to remove the Uniform the error will continuously spam the rpt.
_targetplayer = objectFromNetId "2:1030"; removeUniform _targetplayer;
And you should see the error spamming with the netID of your UniformContainer.

This also triggers for removeVest but not for removeBackpackGlobal.
If you execute on the client there is no error spam in the server rpt.
