.. As it only shows up (for me at least!) when an Ion Storm kicks in or the map's lighting changes drastically.
Yeah, that's what I meant, I get the error sometimes when an Ion Storm starts (on two computers so far).
As a workaround I disabled the random ion storms from all multiplayer maps which had them. However, the error is still quite rare and I left long one-time Ion Storms enabled (in those maps which have one).
