Network Checksum Mismatch Errors

We are building our game for 4.23, and when we join our game, we get checksum errors with our weapon blueprint. The player is then disconnected from the game. Does anyone know why this would be happening?

Looks like one of our players had a client build of the game that didn’t match the servers version of the game, and this is what caused the issue.
