Been having issues since the update as well. On Adamantoise and Famfrit. Some random 90k errors that happen when running around, not after or during a zone.

Also some random lag spikes that last about 2-3 seconds each. Just enough to make me go nuts as a healer in dungeons. It's a really uneasy feeling watching the tank at full health on a boss, then lag, then see tank at half or less health.

Edit: In Florida with Bright House cable internet.
