I know there was a thread explaining using xnb node for packing/unpacking files but I'm still unsure of how to use it. For example I unpacked Abigail.xnb dialogue, changed up the yaml file and I couldn't figure out how to repack it. I'm still really new to using command prompt so this is all foreign language to me ;-; Thanks in advance!
If you can't repack the file after you've edited it, that means you have something going on with the edited file. Sometimes, something as little as missing a quotation mark will result in the file not repacking. You should double check everything, see if anything is wrong, and if you still can't find the error, share the .yaml file here so we can try and find it!
