Hey, could this be related to custom vending?

It technically could be, but that is a vanilla Rust function that the plugin tries to disable for customized vending machines. I didn't have time to test on staging besides checking for compilation errors, but if there is an issue here, I can review after work today (approximately 8 hours after the Rust update).
