I do not know if it was because I changed Servers but I had a few Perks and now they are all gone, haven't read about them expiring as well. (sorry if this was answered already)
If you don't see the perks, please, make a screenshot of your perks window (the window where you can activate/deactivate them).
Perks do not expire and only disappear when they are used. Changing servers don't affect perks.
Note that if you have a round-based perk (such as "Miner's luck") activated and enter the game (step on the field even for a second), it counts as using it in the round. Entering the game in different rooms/servers counts as separate rounds. So by entering games on may servers simultaneously it's possible to lose many of them quickly.
If your character is staying on the field with a time-based perk (such as "Autoshield") activated simultaneously in several servers/rooms, then each server/room will subtract it's own time from the perk and it's also possibly to lose a lot of time quickly.
If you only observe games in any number of servers (without the character stepping on the field), it doesn't affect perks.
