Server Crash with "Invalid Player Data" when Cataclysm Boss Charm, Samsara Boss Charm, and Boss Rush Charm are Equipped at the Same Time

[InputandOutput]

Hello P1neapplell0,
I encountered a fatal bug that occurs when I equip the charms from TCR Core crafted after defeating all cataclysm bosses, Samsara bosses, and completing boss rush at the same time. The error occurs with a fresh install of TCR 2.2.8.3. with TCR Core 2.7.19, though I am running my Minecraft singleplayer instance on Linux. The error snippet is attached below.

(Interestingly enough, it also causes a coredump for my minecraft instance, though it's very difficult to interpret for me).

Updating TCR Core to 2.7.20 did not resolve the issue. Also, I'm unsure whether the boss rush charm is the sole issue or if equipping all the charms resulted in the crash, since the Catalcysm and Samsara charms were equipped and there was no issue.

Note that my issue occurs when I equip the charms at the same time, exit the world, then try to rejoin.

After testing, I realized that just equipping the badge from the boss rush only results in the issue too. It seems that the badge is somehow breaking?

Edit: removing the badge using the "Reliable Remover" mod seems to resolve the issue, though I had to remove all badges from myself to fix it.
