Here’s how to reproduce:
- Type a message (E.g. “War Thunder has a lot of bugs!”) in the chat box but don’t submit
- Get spawned in the air as a bomber (or fighter but not tested)
- The chat text box will be empty, but click it anyways and press return. This will submit the message “War Thunder has a lot of bugs!” that you typed previously even though the text box remains empty.
- After returning to your tank, click the chat text box, type anything (E.g. " Please fix existing issues before making questionable changes to maps again."), and press return. Your previous message will be reposted with whatever you just typed following it. From my example, the result will be a chat message that reads “War Thunder has a lot of bugs! Please fix existing issues before making questionable changes to maps again.”
