Exhaustion 4 still used system.attributes.hp.max which is not available anymore. We are now supposed to use system.attributes.hp.tempmax which has not been implemented yet it seems. I have fixed it myself...

I fixed it by going in the modules folder and finding the module. Open this file: "\AppData\Local\FoundryVTT\Data\modules\dfreds-convenient-effects\scripts\effects\effect-definitions.js" And change key: 'system.attributes.hp.max', mode: CONST.ACTIVE_EFFECT_MODES.MULTIPLY, value: '0.5', priority: 5, With: key: 'system.attributes.hp.tempmax',...

Not sure to be honest with you. But you can always check if it has been changed or not by going into that file.

@DFreds  Not sure but I changed in the file itself and now exhaustion 4 comes up with this (see the image). And it seems to be working for me....
