Unless I've done something wrong, Inventory Helpers doesn't recognise MCA companions despite having the 'Companion Share' dialogue topic. The containers work fine and I installed Emma's Constance companion to check whether the fault lay with Inventory Helpers. The 'Items' dialogue topic shows up with Constance so the problem would seem to lie with MCA.

I have searched far and wide for a patch/solution and come up empty. Does someone know how I could solve this or even suggest a more universal substitute for Inventory Helpers?

edit. Rather than start a new thread:

I made a patch for Morrowind Inhabitants Freeform and Syclonix's Herbalism for Purists (namely, a slight chance of getting a quest ingredient instead of a vanilla ingredient). Have I re-invented the wheel or would there be some interest in such a thing?

After a lot of reading and head scratching, I deleted the 'minimumProfit >= 0' check from the 'items' dialogue topic in Inventory Helpers and this has worked. What other consequences of doing this there might be, I don't know.
