In the last version, I'm seeing a strange rotating debuff on the adds I hit.

Any ideas ?

No clue, someone else posted the exact same issue a few days ago. Apparently it was solved by re-downloading the files.

But I have no idea what the cause could be...

I tried that a few times, I even installed the updater you have. Still seeing the same thing. I'll try to get more info about it.

Try the latest version and see if this issue persists.

The last release seems to fix this problem, what was it?

Could have been because I changed how the repo handled file endings a few days ago. But I feel like that wouldn't have impacted the attached files of the releases.

So I'm still not completely sure if me reverting that fixed it . Or if it was unrelated and there was some different issue all together.

Downloaded the addon from here caused this issue a couple of days ago.

And downloaded from here(latest release version)，it was solved.

I use a tool to download the addon and check update(TidyPlatesContinued.toc).
