When the first player loads their character sheet, the next player's character sheet is replaced with the first player's. This overwrites the cloud storage version as well.
This has been observed in a custom character sheet template.
Steps to reproduce:
  1. create a custom template
  2. fill it out twice
  3. have one player join the game and load one of the sheets from their binder
  4. have another player join the game and load the other sheet from their binder
