Custom Battles Netcode Members Bug

Currently, some CBs are unable to appear on the menu. Due to what rumour has as the same hacker who previously did the now taken-down AA-20 Nord and instant-kick/instant-kill netcode bugs, Custom Battle member counts now freeze at 64 and do not decrease, even if members leave the custom battle, causing battles to fill up with empty slots and eventually crash.

When can we expect some sort of fix for this?
