Its working for me ytd and I am experiencing lags today too.Mate as previously stated I have gained 9 mil fishing xp until an update.
Just because you deny the existence of a bug doesn't make it so.
I'll be retesting today to see if it was runemate that was the issue. I'll post back after an 8 hour proggy
Please see below a video outlining the issue
As I said, previously gotten 9 mil xp. Now i cant get 100k xp
I think its not the bot's problem but the runescape server.
