Identical error messages stacking on top of each other

[loongemperor]

When an error occurs, it results in lots of error popup messages stacking on top of each other.

I go to sleep, wake up, eat breakfast... it has been 12 hours since I last checked F95Checker. It checks for update every 10 minutes. 10 min * 12 hours = 72 identical error popup messages stacked one on top of each other.
I need to click through them one by one.

So far I have seen this happen with:

1. thread moved/deleted. "do you want to convert it into a custom game"
2. every time new tags are added to F95. so I get a massive stack of errors about unrecognized tag.
