Mod Easty posted in the Official Forum's Recent Game Updates:
The current system update is to fix the following issues:
-Players crashing their clients in OpenGL mode due to a certain environment map.
-Fix the Seers "walk around the statue" task.
-Revert the "Spike Trap" haircut to how it was originally.
That does seem very small, I wonder if it was merely the highlight of the update and if there were a lot of small hotfixes as well? If not, I find it surprising.
