This bug is serious and breaks backwards-compatibility with almost all maps that got optimized with Vex' map optimizer. INCLUDING maps made entirely in GUI. This is a serious thing and needs to be fixed yesterday, not in 2 months. As for me, I can not release any new versions despite having fixed my Newgen install, as a manual retrofix for the messed up order IDs might backfire as soon as blizzard patches the order IDs back. We (speaking for the whole community here, sorry) desperately need an ETA on this. Or at least an official word by blizzard if the new order IDs are going to stay or not. At least let us know if this is a permanent change or not, so we can adapt.
