BSPC process fails during bsp map generated with -meta switc

[KoS]

I only map for Single Player RTCW. I used q3ma2 with –meta switch before to make bsp file and after I bspc to produce 2 aas files.
But from some time I cannot bspc my maps longer if I use –meta switch. I guess this problem appeared in recent version of q3map2. How I can fix it? I get following error while bspc –meta switched bsp:

Error:
No entities inside
Leaked

For now I just not use –meta switch and bspc goes very good.

You MUST use the -forcesidesvisible switch for bspc if using -meta.

OK I didn't know that

Thanks for help!
