Posting this here since it has the most visibility:

Recent 256 release does NOT fix importing bugs of 254 and 255. In fact, its release blocks 253, the working import/export version, from cloud syncing.

Not surprised....sadly...

Hi everyone, rather than responding in all the various related threads related to the last few RW builds 253-256, I've opened a new thread which I intend to be a central place for me to respond to these issues and provide information:

An important note discussed in more detail in that thread is that we've now reduced the required build to access the server back down to 253 (with caveats). Also, if you experienced import/export issues in builds 255-256 that were not present in build 253, please take a look at the instructions there. Thank you!
