Yeah, I've made a note and will look into it later.
In case you're wondering about the progress of these bug reports, I'm currently working on pushing out the tech tree changes asap. I will then take care of the bugs while a playable version of the new tree is available for people to test on a separate branch. The tech tree changes will only be merged in after all bug reports have been addressed so people can get the fixes while staying on the old tree if they want.
