Can't test the game. (haxelib mbs?)

I've opened my project on a new machine and now it says:

[haxelib] Error: Could not find haxelib "mbs", does it need to be installed?

What should I do?

Does your new machine have a different version of Stencyl on it?

Yes. I’ve just downloaded the latest built. Why?

My best guess, based on what I could find mbs refers to, is that haxe isn't installed correctly on your new machine.

So what should I do then? How to install it correctly?

Same error here with 10534 on mac. Seems that haxelib isn't installed correctly, or that Stencyl can't find it. Something wrong with Project.xml? Anyway, it's beyond my abilities unfortunately.

This was reported on the issue tracker, and is now fixed.

I've downloaded the new build and now it says:

Failed: Running Android

I attached the logfile.

On my old machine with Build 10417 it also cannot test on Android. It throws a bit more errors but still it looks like Hex problem. I attached the log

I also tried on two other computers and also failed. I am pretty sure it's not the game. The game is on AppStore already. I attached two other logfiles as well.

Log file number 2 is another issue. Don't know what to do about it off-hand, but I can look into it later with you if you want.
Log files number 3 and 4 are both because they're old builds of Stencyl. They'll need to be updated to fix some gradle urls that have dropped http support recently.

The only one that's specifically a recent bug is log file number 1. I'm currently looking into this with somebody on Discord. If you want to help, feel free to drop by the #bugs channel.
