[1.1] Crash in Horadric

[renaudbedard]

After filling the two "In" ports of the mission panel in Horadric with the cargo contents, and getting the "Error" display, linking one of the "In" ports back into the cargo (my logic was to empty the mission ports back into the cargo) causes the game to crash.

It looks like I shouldn't be able to link the "In" ports to anything as a source, but the game lets me do it regardless.
