[Since FlatSprites] Changing to chasecam with a +FlatSprite in view crashes GZDoom

[AFADoomer]

If you have flat sprites in view on a map and turn chasecam on (or run in front of a mirror, apparently, also), the engine crashes.

Sample .pk7 here: http://afadoomer.com/files/FlatSprite.pk7

It's just UNKNA0 set as a flatsprite... Summon 'test' in a map and then run 'chase'. The engine (currently running the 19 Jul dev build) will crash. Software renderer does not crash (and, of course, doesn't support flat sprites, so I think that's expected).

On an unrelated note, the 64-bit dev builds just hard crash with no dump or logs... Is that expected?

This was already fixed.

I saw the commit after I posted this, and just now saw the closed bug thread. Sorry.

Thanks!
