Are you sure you have not mixed Beta 1 and Beta 2 frameworks / client and server implementations? Part of the reason we did not release the beta publically is because the API and the messaging system has (and may continue to) change between releases, leaving beta n -1 implementations not compatible with beta n.
I’ve never seen those issues in any of the betas when they you make sure all of your servers, & clients use the same framework revision across all of your implementations.
