30 minute 2x drop D/C

Describe the problem. Be as specific as possible!:

Using 2x drop 30min personal rep causes the game to lock up and D/C after about a minute. I have no issues with any other rep buffs, like the 15 min buffs or EXP buffs, and I have no lag issues before or after I cast the buff or when I re-log.

 Images of problem

No pictures, as I didn't really expect it. This issue has actually happened twice, but I thought it was a coincidence the first time. I've only been having this problem for about a month, but I was able to use it before with no problems.

Just wondering if this has happened to anyone else.

Yes, happened to me. Just thought it was a regular lag moment
