Yes!, but you need to place the $memory tag in the cast you want to be persistent!

Dear Jagonz, already bought this plugin, but had problem with casts events. I've did everything like in description, but my events is not saved. I put $memory tag into notes field of that event, set category to none. Created common event that has EvenMemory.cs in C# management, and this did strange thing to me. It's like it stretches the graphics of those events and the events change positions, too... Not sure how to describe this ,but maybe I could send you a video somehow?
