Javascript Modules for scripting; Scene graph improvements; Preview improvements & more.
Clearing the cache did not help in my case.
As usual, if you run in to a bug or issue in Construct 3, please post it to the GitHub issue tracker here:
github.com/Scirra/Construct-3-bugs
You must follow the bug report guidelines or your issue will be closed without investigation.
But the issue is with loading 3rd party plugins, as far as I know c3p files with 3rd party plugins are not accepted for bug reports.
How would I go about reporting something like this?
If it works in r218 and doesn't work in r225, you can file an issue for it involving a third party addon - but note if the problem is in the third party addon itself the addon developer will have to fix it.
