I notice when I use this mod in conjunction with TabbyChat 2, RPG HUD's chat ends up overriding this mod. It ends up looking like this:

Instead of like this:

I also can't seem to turn off RPG Hud's rendering system in order to let TabbyChat 2 render.

I made an issue regarding the same problem on TC2's issue page.

This problem is known to me and was previously fixed (there is a setting for it - something like render vanilla chat). Have you tried that? As far as I know that should do the trick.

I tried that, even using the prevent rendering option and it still uses RPG Hud's chat design instead of TC2

Actually, what ends up happening when I use the Prevent rendering option, it makes the entire chat box vanish

I played around with the settings more and fixed the bug. I had to turn on Force Render and Render Vanilla Element in order to make the gui not vanish. Thanks for the tip!
