Stall

# Heyo!
Love the mod, have a question, and an Issue. Issue first.
1. Using this mod my game stalled and had to be forced killed as it would never recover.
2. Can we get a setting to only allow multiple ore types if they share an ore dictionary entry?

## Version Information
- Minecraft 1.12.2
- Forge: 14.23.5.2807
- Veining: 1.3.2

## Report Information
Game froze and never recovered.

## Steps to Reproduce
1. Set settings to have on block spacing between ores
2. And change it to effect multiple types of ores.
3. Mine a large group of ores I suppose.

## Forge Log
[HERE](https://gist.github.com/bookerthegeek/caa5274983105d4520ffe44cfe2c6aef) is the console log.

## Log
[HERE](https://gist.github.com/bookerthegeek/3aa970c116ae13402672a8546a13b5eb) is the stall report.

Start by reviewing the linked Forge console log and stall report, then reproduce the freeze with one-block spacing and multiple ore types enabled in Minecraft 1.12.2. Confirm whether mining a large ore group causes an unrecoverable stall; done means the freeze is prevented or its cause is clearly isolated, with the requested ore-dictionary behavior separately clarified.
