Moveable mounted guns (func_tank***) are not controllable by the player with VJolt

[steadyfield]

The game I was using with VJolt is the original HL2. The map I was testing is a custom-made map by me, named as coop_desert_antlion_h. The test map can be downloaded from the attachment file. In the custom-made map, there are several mounted guns (func_tank*** entities), some of which is fixed (not moveable), and the others are moveable by setting the parent of the func_tank*** to func_physbox. The problem is that I found the non-moveable func_tank***s are controllable, but the moveable func_tank***s are not controllable by the player, with VJolt Physics Engine, while the mounted guns are all working fine with the original VPhysics Engine. coop_desert_antlion_h.zip
