Processing patterns with ore dict substitution get stuck

[m-mueller678]

When creating a processing pattern with ore-dict substitution enabled and requesting it, crafting gest stuck at 'scheduled'. No items are pushed. In this case, the interface points at a vanilla chest, but it happens with other inventories as well. This only happens if the system uses a mix of items as ingredients. In the below screenshot, it is 2 different kinds of LV circuit. After removing one kind of Circuit and adding more of the other, it works as expected. The pattern can be created via NEI shift clicking or manually. The bug occurs either way.

This is AE2 rv3-beta-292-GTNH in GTNH in 2.5.1 in single player.
