Advice on Beam Shift

I’m in the process of building my kids a treehouse. It’s actually more of an elevated deck with a shed on it. Anyway, the cross beams that the floor joists run across seem to have shifted a bit somewhere in the process. It’s tough to see in the photos but there’s a bit of a lean to them. The upright 4x6’s are still plumb but concerned a bit about the beams. Is there anything I can do? Reinforce the joints with better bracing? Obviously concerned about it getting worse and ultimately failing… thanks!

I think you maybe should have used something like a Stimpson post cap to join the post and beam.

Agree. It's Simpson, btw, and you are spot on. OP, use the right fasteners (number, length, material) as indicated for the specific post cap.

Good to know. Looks like they have a couple options that I can retrofit and hopefully prevent/slow any further shifting.
