Hello,
This livery after the last update (23Dec) makes the sim hang at 100% loading screen on my end. I have a lot of A320 liveries but this seems to be the only one. (also some other planes skins do the same but they are made by other creators.
Can you confirm?
On the MFS forum people said that some addons with apostrophe in the file name structure might be at fault. Could it some other character too? Although I couldn't find one but maybe a polish character is normally replaced or shown as a normal one?
This is the thread:

EDIT

For other people that want to solve this issue. Go to this other livery and download it:
https://flightsim.to/file/5550/grumman-goose-8s9-aeronavale
It is for another airplane but it's not the point. Inside there is an exe file that makes json files. The file that has the problem is the
layout.json
You can use the autojson.exe program to fix any other json files from other liveries. Including this one.
So put the autojson.exe on your desktop. Run it then use the directory button to point to this livery folder. Once the folder is selected the program analyzes the folder and shows the results. Hit save and now save the new layout.json file in that folder overriding the old one. If you want you can make a backup first. I did to see the differences and I found the problem this way.
Then you are all set the livery will work game will load.
The difference in this case were these lines:

{
"path": "SimObjects/AirPlanes/Asobo_A320_NEO-LOTFOLK/aircraft.cfg",
"size": 4054,
"date": 1606648950887
},
{
"path": "SimObjects/AirPlanes/Asobo_A320_NEO-LOTFOLK/MODEL.AIA320/model.cfg",
"size": 249,
"date": 1599878289959
},
{
"path": "SimObjects/AirPlanes/Asobo_A320_NEO-LOTFOLK/MODEL.MAIN/model.cfg",
"size": 938,
"date": 1604112576201
},

They were marked as different by notepad++ I am not sure if just the values or something about the encoding because it's hard to see any other differences.

rly good work

Thanks for all the different LOT liveries! Amazing work!

Great livery, looks amazing! Thank you.
