Going back to the issue here:
https://forums.alliedmods.net/showth...89#post2211589
I am running a development version of the plugin in question (I forgot to disable auto-updating.) When Updater checks for an update, it sees that the version number is different, and it downloads the new version. It deletes the old version, but then fails to rename the new file to what the old file was. The new file has all characters in its filename converted to lower-case, and has the .temp extension tacked on. This bug now seems to happen CONSISTENTLY on my development server.
Perhaps there is an issue with capitalization and SteamTools?
No error logs are created, and the Updater.log indicates nothing but success.
I will remove the capital letter and see if the error continues tomorrow.
