Tiberius Station crash - polymer, explosive barrels, dynamic lights, code fix (workaround)

The room with the boss in Tiberius Station crashes every time when I blow up the barrels, when using Polymer and with all dynamic lights. Same issue it seems as in https://forums.duke4.net/topic/12084-tiberius-station-explosive-barrel-crash/ where the first commit known bad was e67e5391 (it's a big one, so hard to pinpoint what exactly did it)

I was able to get this to not crash while continuing to use Polymer with full dynamic lights with a small patch. It's not a real fix, as in it doesn't fix what the root cause is (which I can't determine) but maybe points in the right direction.

don't know why it's so high but just bailing for that frame when there are more than 10 million indices keeps things running and I rather doubt there should ever be that many
