All Mods disappeared

Well Support is a blatant joke:

short: returned on monday after years long break and all was like i left behind. Yesterday my Account went from 7.2m Gp to 6,5m because all equipped mods were gone.

 I can not farm new mods because as soon as I equip a second mod, the former disappears. Posted a vid on reddit showing the bug.

Support People introduce themselves within 5 Minutes with always changing names and are not even able to read my bug report or to review the screen Recordings they explicetly asked for. 
I went through all troubleshooting guides with them. But now they simply closed the ticket. 

playing without mods is a huge disadvantage. Anyone has an idea ? I would even consider to start farm new mods… but i need to be able to equip them at least.
