Xlights version 2021.11
I was updating my xsq files when I got a message that the gif file I was calling out was no where to be found.
I used tools to find the timing of the error; But when I opened the picture effect the file name was correct.
Using a XML editor I opened the xsq file for that sequence I found that it was trying to load a file name that was messed up. It follows the " ' " character; as in "Don't". I've never had this issue before (been running this sequences for years).
I repaired the file name in the xsq sequence file and all is good.
BTW: this sequence is the only one to call a gif file with the special character.
