Hi all,
I managed to find some time to take a look at World Boxing Manager again, and I've updated a few things based on suggestions in the forums (yes, I do check in from time to time!)
I've restructured events so that you can now book multiple fighters on the same card. This was a frequently requested feature, so hopefully you like it! Note that income from networks booked for that event only counts once, so there's still a reason NOT to book everyone on the same card.
Thanks to a suggestion from the discussion forums, I've tweaked sparring gains so that using instructions during sparring matches results in additional gains for certain attributes. For instance, using "Use the rear hook more!" will result in gains for Rear Hook. This does, however, depend on the fighter's style, so using tactics like "Wait for an Opening!" or "Stick and Move!" during sparring won't help a Slugger.
The bad news is that some of the issues that have been bothering you, like world titles not being defendable, etc, still haven't been solved. I'm not able to reproduce the problems on my end, so I'm still poring over the codebase to see where the issue might be happening. Hopefully I'll be able to track it down at some point.
Thanks for playing!
