Your guess is right. Just look into the first post. The huge red text is hard to miss.
tbh, I missed it at first, since the red on grey messed with my vision 
in the first post it says that forge 1445-1481 breaks GTMP, thats why I though forge .1428 would work. But anyhow, gonna test with forge .1490 now and just hope for the best 
(thanks for the fast reply btw)
