strange on-start bug

[TheCluelessSpectator]

I'm not sure if this is a conflict or not, but I've disabled every other mod, and yet the issue persists. It starts every time the map loads, spewing this out

[Dynamic Weapon Reverb] lua/includes/extensions/net.lua:142: bad argument #1 to 'pairs' (table expected, got nil)
  1. pairs - [C]:-1
   2. WriteTable - lua/includes/extensions/net.lua:142
    3. v - lua/autorun/server/dwr_server.lua:65
     4. unknown - lua/includes/modules/hook.lua:102

It also breaks my c-hands, strips me of the physgun and toolgun I'd normally spawn with, makes me unable to use my flashlight, and makes my playermodel (I assume) a placeholder one.

Seems to hog net messaging, and dwr_sync_blacklist is always the culprit. Other mods/functions that use net messaging also get stopped by this message.

[Dynamic Weapon Reverb] Warning! A net message (dwr_sync_blacklist) is already started! Discarding in favor of the new message! (dwr_EntityFireBullets_networked)
  1. networkGunshotEvent - lua/autorun/server/dwr_server.lua:100

Here's a video of it in action. Second time loading into a map. Couldn't seem to get the video uploaded here, so I put it in a streamable link. LMK if it's expired.
