Platinum's Halawai Boulevard race softlocks when the race finishes. The race "continues" in the background with no way to close the results screen. It appears to be related to the number of AI drivers. With 5 it always works normally.
This file: Took the IGE from the vanilla game, extended the race to Platinum's layout (using less checkpoints), set to 5 bots, $10000 prize, other settings untouched.
Install: Just overwrite RSFE0024.IGE in \Euro\Bnk\Ige
