So, I have 2 saved skill presets: 1 for PVE and one for PVP.

I customized my UI so I can see my cooldowns, and that is fine. I have assigned skills to these skill boxes from the UI, but everytime I switch skill preset to access the correct PVP or PVE add-ons (so that I dont have to manually switch skill add-ons everytime I enter Arena od Solare), all the skill cooldown slots I assigned to the UI get shuffles around. I have to always reassign the cooldowns to the right slot all over again. Furtermore, the chat box settings I assign keep reverting as well.

This is a disaster. Really. It is not something we should have to go through everytime, and I can't imagine it to be a big fix. If anyone has a solution, do tell.

FYI, I have tried both going to character select and leaving the game correctly, but that did not seem to save it.

Hi there, have you saved the Skill Preset since making the CD slots? The CD slots are saved with the presets (or at least they should be if everything is working), but you have to save the preset again after setting the slots up. Please try that once more, to see if that works.
