The Veteran's chest gives... too much gold. My gold rolled over to negative numbers after I grabbed it. Need to either add a few bits where you are storing gold or prevent it from rolling over.
Wow, not normally the type to post this, but my best season:
50 appearances
100 goals
20 Hat Tricks
314 Passes
35 Man of the Match
27 Assists
9.5 Average Rating
...And won both Cups and the English Premier League.
Suggestion for the new meter: Add expected time to next level. Since you have the exp per second it should be easy to implement as it's just simple division.
I am working on this fix. Turns out to be a bit more complicated than I expected so it is taking a little longer.
