I want an NPC to travel from their Editor Position, over to a shop in the IC, loiter in the shop till 8pm, and then leave and return to their Editor position.

I thought I could do this just with two travel packages.

Time: 8
Travel
X Marker

Time:20
Travel
Editor Location

However as soon as they reach the X Marker, they turn around and start heading back, having dropped into the Wander package that takes up that time frame on days they aren't traveling.

Is there a way to flag the Travel package to not end till the next travel package starts, or do I need to insert a wander package between them?
