I've completed some time ago some exchange quest in this category, but I cannot repeat some of them. All of these quests accept "Coin The Technician 1". Not working: "Vacuum Tubes", "Basic Circuit Board", "Resitors", "Rubber Ingots".
When i press Detect/Sumbit nothing happens even though I have coins, I don't have any issue repeating any other quests than these.
Also it is only my issue as someone tried to repeat them and they didn't have any issue.
I have tried to reinstall client (removed whole technic folder from appdata). Also issue persists for days so server restarts don't help.
I found out my party member, Alarien, has these quests bugged. They have negative cooldown which is still decreasing. All bugged quests are the ones i have listed above.
