I thought I had the latest version (I re-downloaded the installer from the website to kind of start over). But I’ll post the version of that when I get home tonight.
Looks like I had haxe 3.1.3 somehow. I updated to 3.2.1 and now openfl test linux or openfl test neko or either of those commands with test replaced with build seem to do nothing. I see files created in the Export directory but these commands seem to be non-op now.
