Hi Silvers,
I'm not sure when this conflict/break started but in a recent update (last known working 2022, haven't really tinkered with things much since then) info editor broke the functionality of using Lux's L4D1 Music Proxy in unison with more than four survivors on an L4D1 map.

After some trial and error I confirmed removing info editor allows it to work as normal. Anything I can tweak in one of the config files to allow them to work together or is it a code issue?
