The weapon scripts and resource files themselves are being reloaded fine (except those from the list in #2), but somehow the game still keeps looking for those extra materials.

I noticed this tonight in the official L4D2 build along with some strange bugs regarding sound. Seems on some custom campaigns (using mapname_level_sounds.txt), this material "spam" in console, along with the absence of special infected sounds (primarily when pinned, boomed, jockey'd etc.) seems to be a pretty consistent bug.

The sound absence happened after disconnecting from a custom campaign, and then Quick Matching into another campaign. If I start a lobby, launch it, I will hear the special infected sounds. But, even after starting a lobby (for an official campaign), exiting, and Quick Matching into another campaign, the sounds are gone again. Seems something buggy with Quick Matching after having launched a custom campaign. Like the official sounds aren't getting properly restored despite:


I would have tested this in the Beta build but there is no Quick Matching, because of no servers obviously.

Can any mods take a look at this?

I know CommonDrop had said that the campaigns larger than 200mb were just a"wiggle room" compression problem, but is this limit something that can be adjusted, or are we stuck at this size?
