[0.16.7] Crash in LightRenderer::loadLights

[AlcatrazIV]

Was placing belts (by hand) when the game crashed. Full log, last autosave, and zipped mods directory are attached.

I continued playing this save. About thirty minutes in, and it didn't crash again so far, so this seems to be a sporadic issue.

Stacktrace:

This looks quite random. The code in this part haven't been touched in a long time. To be sure I loaded your save with the mod in debug mode and checked its consistency and everything seems to be fine.
So only explanation I can think of is either random hardware bug, or some other (threading?) issue.
I'm moving this to pending.

I've seen this report several times now but nobody has any consistent way to reproduce it and as Kovarex said that code hasn't changed in a *long* time. Not that there can't be a bug in it but without some way to reproduce the crash (or a crash dump) there's not much we can do.
