Find and replace bug

i need to do a batch find and replace on about 200 files. i can open them all then hit replace all, then publish and it works fine. but when i save the file, close it and re-open, it’s like nothing has been changed. the only way i can overcome this is by opening the actionscript window and adding a space then removing it, and then saving the document.

anyone else encountered this bug? i can’t find anything about it online. and i have to find a way to overcome this issue, otherwise this work will be the death of me…

any suggestions?
