On each of the major sector 42 raid attempts on Rimor this weekend, one on Saturday and one on Sunday, pet users lost the ability to control their pets for an extended period of time (about 15-20 minutes). Even once they regained the ability to control pets, the behavior was patchy, and pets wouldn't respond occasionally for the next 45 minutes, until we left the sector.
I know at least one pet user who recast pets, and was still unable to command them.
These were the 4th and 5th major raids on the sector (where there were 80+ people) and in the first 3, pet owners never had problems. I wrote the problems on Saturday off to server issues or generic AO lag/inability to deal with crowds (see how well they have trained us to ignore things?) but after the exact same problem on Sunday, I think something must have gotten borked in the last patch.
Have other pet owners seen problems in other 42 raids, or outside of 42?
