Using latest forge for 1.12.2 and latest version of this mod causes some weird bugs with the health bar, rendering just green or white, and is misplaced, with no way of moving it around. See the attachment.

this issue may have been fixed by v1.12.2-1.4-beta.2. Please notify me if so, so I can close this issue.

I can't reproduce this with just Better HUD and Mantle, are you sure?

I found what is likely the same issue. It is caused by Mantle, and has not been fixed as of beta 3.

The 'misplaced' aspect I can reproduce with Beta 3.

Repro steps are:

1. Have health, armor, food, and experience bar all Enabled
2. Disable the experience bar
3. Note that Armor and Food move downward closer to the Hotbar, but the Health bar does not move - so now Armor is slightly overlapping it.

@DPattee The issue is confirmed a problem with Mantle, I have opened an issue there.

Another option would be to start with a base Forge installation and add mods one at a time, or test each mod individually. It may be difficult to figure out the culprit(s), because it could be any combination of mods, but it's most likely just one. I have never seen this problem myself, and as far as I know, Better HUD should reset at least the colour and texture before drawing.

Do you have any other mods installed that change the health bar? It looks like another mod is cancelling the event and rendering their own bar in the vanilla position.

I use a bunch of mods, none really adding much things to the GUI. To my knowledge, nothing changes the health and armor gui. And there is not really anything popping up in the game log file

I can try locating the problem by uninstalling mods, one by one, but that will take time as my modpack takes 10 mins to launch each time. 250 mods installed.

Closing since the issue is solved in Mantle. If this issue occurs again, please leave a comment and I'll reopen.
