I did not know about it.

If this is true, it will be a big pain for all developers of assets.

The best way to work around this, at least for now:

Thread.CurrentThread.CurrentCulture = System.Globalization.CultureInfo.InvariantCulture;

Thanks for this fix, it saved me some time, but it's not the only one in the plugin now.
In Unity 2018.3, the default conversion is now Culture.CurrentCulture !!!
I'm French and all floating or double values are parsed with an expected "," by default ... sad
I need to patch your plugin to use InvariantCulture each time a Double is parsed.
Could you take care of that changement from Unity 2018.3 in your next versions please ?
Thanks

Thanks for your modification.
The next version of Online Maps will contain this.

This is not a bug request, rather a small evolution request to update OnlineMapsXML.cs in order to use invariantCulture while parsing some types (i.e Doubles, by example) that causes exception if not done.

The modification concern Lines 628-630 in \Infinity Code\Online Maps\Scripts\XML\OnlineMapsXML.cs
Would it be possible to change :

[...]
        try
        {
            MethodInfo method = OnlineMapsReflectionHelper.GetMethod(underlyingType, "Parse", new[] {typeof (string)});
            if (method != null) obj = (T)method.Invoke(null, new[] { value });
        }
[...]

TO

[...]
        try
        {
            MethodInfo method = OnlineMapsReflectionHelper.GetMethod(underlyingType, "Parse", new Type[] { typeof(string), typeof(CultureInfo) });
            CultureInfo c = CultureInfo.InvariantCulture;
            if (method != null) obj = (T)method.Invoke(null, new object[] { value, c });
        }
[...]

..This would prevent us to patch OnlineMapsXML code every time we update the pluggin

Thanks !
