ARSENAL WORK HERE PERFECTLY

what is your view distance setting ?

Memory leak after the update.
Because of that, the global number of player keep decreasing dramatically , you can check on steam .
i believe this should be a priority instead or worry about rock in the wrong place or weapon sit , ground shaking .
About trying to reproduce the error in RC branch , i did try to reproduce the error but fail because most of the time this happen while playing in a high volume server .
I can also add this problem can also be reproduce via the 3d editor using tonao map , where by switching to different location to rapidly using the map and 3d view.
