That would be true if they knew what software build on which you saw the bug. Unless you tell them, by the time they get to reviewing your issue, the software might have already gone through multiple updates and the issue may have been fixed. It’s an extremely important piece of information for any debugging process.
Sure, they might be able to determine what version by the date of submission (I assume they track that), but, I have no issue making their jobs easier. Another issue would be offline players, they may not be on the latest update.
It’s possible, also, that they thought they fixed the bug, but didn’t. Remember, Zendesk just helps them sort the likely hundreds or thousands of reports they get per day. “Solved” only means it’s been processed and either rejected or put in the debugging queue. It would be nice if they communicated whether or not the report was rejected.
