There seems to be a bug in the hotfix that affects the naming pattern of newly created proxies.
If an asset doesn't have a number at the end, '001' is being appended to it.
If it ends with a number, this gets incremented by 1, ie. 'Box 01' becomes 'crp_Box 02'.
This happens only when exporting to single proxy, creating multiple at once keeps the original names of the assets.
Please refer to the attached screenshots for more details.
One more thing, that isn't actually a bug but a big inconvenience: it would be nice if the script actually warned before overwriting existing proxies. Right now it just does it without giving the user a slightest clue of what has happened.
