Version: 2.4-dev IA-32 Mar 21 2012 Win32 RELEASE
Map: Little forest

A certain plant type has two unpassable squares, even though pathfinding (option Confirm action is set to Moving only) considers it a valid path. This can cause soldiers to get stuck or to take a detour costing more TU, which in turn can cause not enough TUs to remain to fire, crouch, etc. A screenshot is included to demonstrate this issue; the soldier is unable to take the path the blue line suggests.

Reproduce by standing next to one of these plants and trying to move into one of the offending squares.

Confirmed.

We have two problems here:

1. It's NOT a problem that those branches are NOT walkable. The prob is that the other branches are walkable. I know how to correct that, but I'm not sure if we will like the result for especially this plant (G_BuildForbiddenListForEntity, xDelta = max(1, maxs[0] - mins[0]); )
It would probably be better to make this plant a func_model rather than a misc_model.

2. the drawn line of walking is of course wrong. Investigating...

2. is caused by misc_models not being in the client's forbiddenList.
The line is drawn by CL_ActorTraceMove which uses cl.pathMap.
cl.pathMap is updated by [...] CL_BuildForbiddenList that works different than G_BuildForbiddenList as far as ET_SOLID (the plant) is concerned.
