Do I write this off to "wood moves" or something else?

I built a mesquite table using kiln dried mesquite from a reputable source around a year ago. I am very pleased with how it turned out. I had it in the home for apx. a month when we suffered a fire that resulted in moving everything into storage (conditioned space) for apx. 10 months. When the table was brought back I was relieved to find no damage had occurred during shipment/storage. We are in the house for around 5 weeks when these cracks developed in one plank of the top. No other cracks have shown anywhere else.
I’m wondering if this is just a case of “wood moves” or possibly something else. Cracks do not go all the way through to the bottom and one edge is proud of the surface by apx. 1/32”.
The top is constructed out of 5/4 mesquite that has been epoxy filled for voids/cracks. The epoxy process, as you would imagine was quite lengthy and took 5-6 days to ensure all the cracks/voids were filled completely. I used dominoes for joining the planks together and finished with 5 coats of Arm-R-Seal hand rubbed to 1200 grit.
Maybe someone with a lot of experience in working with mesquite has seen this before or any suggestions are appreciated. It would appear the fix is pretty simple; plane to flat, fill crack with epoxy, and refinish.

Many Thanks,
Hog

Yeah, this is pretty common in my experience working with mesquite. It’s a pretty wood, but has two drawbacks: short(ish) fibers and lots of movement over time. Even a decade after careful drying, you’d think it has stabilized, but new cracks appear when the humidity jumps up or down.

Yes it can be Wood movment and construction. If you connect cleats on the bottom of the table by screwing or gluing the cleats down tightly so the top can’t move it cracks, plus you changed the atmosphere it was in twice. The other issue is as “Sycamoray” stated the kind of wood you use.

Thanks fellas, that’s what I was afraid of. Interesting, guess it’s just something I’ll have to put up with because I REALLY like the wood.
I did attach top (not too tight) using screws but elongated the holes in crossmember to allow for movement.
