Can not open doors to enter Keeleon Castle in Ch. 4 when doing solo hero challenge

[mrmooney]

I may be doing something wrong by not having set some special trigger, but for the life of me, I can not open the magic key doors in Keeleon Castle in Ch.4 with "Orin Strength" after obtaining the NPC in the chapter and when running the solo hero challenge with Cristo. It just says "The lock doesn't turn" like it would in Ch. 5 before acquiring the magic key. Because of that, I can not proceed any further in this seed.
