Oh that's interesting. I'm glad you found something that works. I'm curious though what the difference is between the two filenames if that did fix the problem. Could you show me the filenames and maybe a screenshot or two of your plugin parameters? That might help narrow down why you hit that problem and prevent others from hitting the same problem.
In the meantime I'll continue to try to get the plugin to fail where you had problems, but so far I've still had no luck. Whenever I deploy my test projects the deployed version works no problem. I've had some ideas of what could be causing the problem but being able to get it to fail and crash in the first place has been unproductive so far.
