Area(s) with this issue?

The bug also exists in the original game (RCT2/RCTC)

Describe the issue

Not sure what the upper limit is for food, my guess is 999. But I have a guest who claims to have spent $2400 on 38 items of food. All food is priced at less than $3 so that is not possible. I am guessing the guest has probably purchased 1,037 items. Not sure what the limit is but it appears this issue also applies to drinks and souvenirs. Rides at least stop counting after 255 but it seems the other items roll over at some point.

Steps to reproduce

Guest enters park
Purchases food items over many years
At some point the number rolls over and starts counting again

The value is written to an unsigned 8-bit integer, meaning the largest value it can hold is 255. At 256, it rolls over to 0. So your guest will have bought 294 items of food.

This is essentially the same issue as #21333 , except it doesn’t seem to protect against rollover here (as you already mentioned).

It's still possible the guest bought over a 1000 food items, but that the counter already rolled over 4 times by now.
