@ChrisPerkinsDnD We're having a disagreement about whether a teleportation circle spell will allow a wagon through? Any tips?

Strictly speaking, the circle transports creatures only. For a higher material component cost, I might allow the spell to transport a wagon. https://t.co/JRQK5nV5b3

I got around this with my DM by having all my workers that were constructing an outpost for me carry the materials when teleporting, having multiple dwarves carrying one tree at a time or something.
