Huhu,
I was able to reproduce your problem. I managed to fix this bug. It is running as I remembered it running. However I didn't used it for quite a while now, so I don't know how to test properly. So I would like to ask you (or anyone else, who is/were using this addon) to test, if everything is running fine now.
Edit: It's already updated on alloder.pro:
https://alloder.pro/files/file/277-healer/
As the addon itself is too big for the file limit (150kb) I temporary uploaded it to volafile (it's just there for 2 days) You need to click on the icon left to the filename in order to download. However I did contact the admin of alloder.pro, if I just can upload this inofficial fix to alloder.pro later.
If you get any special error with this version please tell me (or tell me, if everything is fine now)
Greetings,
Buuhuu
