I've just played around a bit with quests and chain events and for me it worked, even if the event chain starts with a Chain event - although I admit it was just one Chain event, not two or three in a row.

Every time something wasn't functioning the way I intended it to, the cause was always that I didn't set the events up properly, e.g. I often forgot to select for which quest the condition should apply. Which doesn't mean the same is true in your case, maybe there IS a bug I wasn't able to reproduce yet.

But is there a reason in your case why you'd want to bother with Chain events at all? Couldn't you just do it like that (using simple even conditions):

Transfer Module (if Quest is complete)
Normal Chain: Transfer Module (if Quest is in progress)
Normal Chain: Guard Talk Statement - Take one step back?

Using Chain events only makes sense if you've got more than one condition that's required to be met (like Quest is complete AND party is facing west).
