The latest MOP offsets are up. You will need to run PQRUPdater.exe to get to PQR v2.1.8. If you do not then use of functions that check position (behind target, etc) may return incorrect values.
I discovered a bug that was introduced in 2.1.7 where the ObjectManager was taking up to 1 second per refresh. It should takes about 4 milliseconds. This has been fixed.
