Fist I was trying to report an issue on support tickets, tried like 10 times to upload a screenshot in several formats and sizes, not a single success. Then I decided to put the screenshot as a link and guess what, when I submited the ticket, it simply vanished. Anyway, since I was not able to send this ticket, I hope someone from CCP look here and fix this.
Issue originally spoted on incursion sites (did not tested on normal pve sites)
While activating the gate to enter an incursion site tried to swap crystals or scripts from weapons / modules won’t work and you get an error of message not found.
