Tested on the new waterbody Ladoga Archipelago, lag and almost impossilble fishing there.
restarted router, restarted PC, checked files, runned dignostics, stopped other software still lagging.
Didn't sent to support dignostics file.
Tested Mosquito, winding rivulet and tung, fishing is normal as yesterday without any lag.
Any clue before sending dignostic file to support?
