Installing DLC broke the Receive Items function

[Hextator]

As the title says, I can no longer use the Receive Items functionality after installing some DLC.

• Hotfix merging and using the Receive Items system both worked just fine up until within a few days of the DLC purchase.
  • It's possible that the Receive Items function was still working on the day of the purchase itself, based on some things I said in a Discord chat on that day, but my memory isn't clear in that regard.
• I still have the ability to load and merge hotfixes.
  • I confirmed this by merging in the custom hotfix that makes enemies spawn with legendary weapons, after which a test run through Lectra City resulted in me encountering one enemy with a Scourge, and another with a Jericho, among some other weapons that were presumably also legendaries, all within short order.
• localhost:9998 never actually acknowledges that a successful connection was made, though the https://c0dycode.github.io/BL3HotfixWebUI/ interface does.
  • I had been using the latter instead for quite some time; I vaguely recall the former not working well before the Receive Items function stopped working, but I'm not sure.
• The usual "0/[max number of hotfixes available]" info card that appears in the bottom left corner of the game's main menu is no longer appearing.
  • I am not sure if it was appearing within the few days I had been playing just before I installed the DLC I purchased, or if I haven't seen it in a while, as I haven't messed with using custom hotfixes in quite some time, but I know that there's normally a third "ad" in that little box, which would indicate the number of hotfixes loaded by B3HM, and it's not there anymore (despite that merging custom hotfixes still works).
• Everything has been reinstalled, and in this order:
  • B3HM itself; both the executable and the DLL.
  • The VC++ redist packages.
  • The game files (they were just verified, which resulted in just 2 files being redownloaded - no clue which ones).
  • The d3d DLL that acts as the plugin loader.
• Logs look good:

Exiting Process...

I have no idea what the hell broke, or how to debug any of these things myself. There doesn't seem to be a repo for the B3HM server, just one for the web UI client.
