in erebus1 map, an assertion in RB_DrawElementsWithCounters() fails

[DanielGibson]

It happens in the erebus1 map (the first of the RoE addon) while the cutscene at the beginning is running, I think about at the time the wall is blown open.

RBDOOM-3-BFG/neo/renderer/tr_backend_draw.cpp

Lines 179 to 181 in dd9b8a8

	if( surf->jointCache )
	{
	if( !verify( renderProgManager.ShaderUsesJoints() ) )

    if( surf->jointCache )
    {
        if( !verify( renderProgManager.ShaderUsesJoints() ) )
            ...

verify() (which calls assert() in debug builds) fails.
This means that surf->jointCache at that point is not NULL, but the used shader - blendlight.vfp according to gdb - does not use joints.

On Linux this currently causes the game to crash in debug builds.

Oh btw, this happens on Windows as well and I'm pretty sure we didn't introduce this bug.
Would be cool if we could fix this anyway :-)
