How to avoid problems
First of all, try to work as much as possible in a unit scale that’s not too big and not too small. You can use the Remember Root Positions button in the Ox Guides from Surface and the Ox Hair from Guides modifiers to avoid changing position during animation or when reopenning a file. Sometimes playing around with the Root Distribution mode in the Ox Guide from Surfaces can fix issues like hair growing in the wrong direction. And of course, you can have a look in the Ephere forum, where users often post their problems. It saves a lot of time and prevents me from getting some serious headaches!
