The save bug is odd. We tested it on three computers, and it saved fine. It should have worked from the desktop folder, but, well, computers are complicated, annoying and hard to predict. The error file should be in shadows_v8_data / output_log.txt. We don't currently have any other bug tracking system than here, no. If the bug is a failure to save, it should be fixed somewhat. It may not succeed in saving, but should keep running and not crash.
The voting has been changed, to operate entirely from the voting screen, accessible from the voting button above the ability and power buttons. This replaced the old voting ability buttons, to unify the UI somewhat. It should allow slightly better instant feedback on how the voting is impacted by your own vote, how much more you'll need to do to swing the vote, and who to target to achieve this.
