One question: can horses still be converted into dreadnoughts, or has it been fixed?

It says that it has been fixed. It was only possible to convert them after saving and loading the game. Actually, if they had noticed it right away, I would have fixed it a long time ago.

It would be better to pack Ivore in a zip file and upload it to the site, as the links become invalid after some time...

Yes, those who wanted to download it had the opportunity to do so.
