Hi Salute,
The issues you mentioned are bugs the team know about. Some community members have shared some tips for finding the prompts on rafts in [Known Issue] Interaction prompts not displaying
As the team are still investigating the rafts vanishing, we would greatly appreciate a bug report of your experiences if you’re happy to do so.
The most common reports of this issue that I’ve seen are players who return to islands and save immediately. Please let me know if this was the case for you and if you experienced any lag or noticed any island elements still loading in when saving.
