Experimental compatibility mode appears to delete crafting ability from assemblers of different qualities when paired with mods that modify assemblers or add tiers of buildings. exact cause is difficult to render out, but disabling experimental compatability mode "restored" craft-ability to higher tier buildings that lose ability to craft the recipes the "common" quality machines could.

(more specific), i added the quality effects fixed mod but when upgrading quality tier of assembler when this mod's option was enabled, some recipes disappear.

(if i understand it correctly), this mod adds crafting categories to recipes which get applied to the AM3, but the mod that modifies the AM3's quality impacts don't get that update of the crafting categories?
