[1.10] Cannot trade wares between me and other ship

[Phinixa]

For some reason its impossible to trade wares between myself and another ship I recently bought. If I order my AI ship to trade with me, it will simply do nothing! Even if I wait some time, nope.
Cleared the order list and tried it again, same result.

However if I do it with my ship being controlled by a pilot, it works!

The ware in question is antimatter cells. I had to work around it by jettisoning the cells and order the AI to pick it up manually which finally worked.

This can't be intended behaviour!
