i sync WoW addons between 2 computers (desk and laptop) using Dropbox... on my laptop the Collectinator addon shows as Modified even though it's not.
on the desk computer i even forced a manual reinstall of the Collectinator addon and it still shows as modified in curse client on my laptop...
I used a recursive SHA-256 checksum of the files under /Addons/ on both my computers, the checksums of all the files match to the last bit but the Curse app on laptop still shows Collectinator as modified.
i submitted bug reports from the curse app on both my desktop and my laptop.. but the app has no support for attaching screenshots so here they are.
edit: forced a reinstall of the addon on laptop by clicking on the Modified button and the app basically re-installed the exact same addon.
I verified the recursive folder checksum after the app finished, no file has changed and the recursive file checksum is the same as before - the only thing that changed is that now curse displays the correct addon version.
