We have been receiving and investigating reports of chat unreliability since the release of our latest game update, Patch 0.7.3. We have reproduced this issue internally and expect that it will require a patch to address. I don’t yet have an ETA for a solution.
We would like to thank you for the reports and apologize for the inconvenience. While we aren’t currently requesting additional information to help us look into this, I’ll post an update if that changes. We appreciate your patience as we investigate this.
