Cannot save bunch of arrays without problem to resource.xml as I get Build error: Expected array values to be separated by , instead of .

Maybe you are right  maybe they keep string... I haven't tested it  I only assumed what I would do.

But how have you managed to compile res with -167 id (as you can see prg)?

Well I did it before I think it reads it as a string, the only difference is the contents of the array.

   <jsonData id="-167">
   [
   [-163.546,54.678,145.345,65.423]
   ]
   </jsonData>

BUILD: ERROR: Rez.mc:40,19: mismatched input '-' expecting {'Method', ID}

I’m gonna replace the minus sign with an m

I’ll need to take a close look at all of them, there’s 641kb worth of them so it’s possible there’s a mistake. 

If you grab the part of the data that's pure JSON, paste it into another file and set the language in VS Code to JS or JSON, you should hopefully see the problem right away.

Do you plan to load into memory 641kB?
