Cannot export - Error exporting: Error: "invalid runtime file"

Hello all,

Trying to export my project to android (which worked a week ago) but now it says "error exporting".

If I open up the web console this is what it shows:

Error exporting: Error: "invalid runtime file"

dqp editor.construct.net/r159/projectResources.js:15

dqg editor.construct.net/r159/projectResources.js:12

dqL editor.construct.net/r159/projectResources.js:12

dqN editor.construct.net/r159/projectResources.js:12

diO editor.construct.net/r159/projectResources.js:15

main.js:159:96312

$d editor.construct.net/r159/main.js:159

​Any ideas?

I have searched with no luck, tried different options (minify/no -minify, compress, dedupe, unsigned apk, debug apk, etc.) but it always fails with this.

Thanks!
