Some block are not built during the build

## Some information
Operating system: Windows 10
Java version: 1.8.0_51 64bit
Minecraft version: 1.16.3
Baritone version: 1.16.1
Fabric : 0.10.6

## Exception, error or logs

[latest.log](https://github.com/cabaletta/baritone/files/5483922/latest.log)

## How to reproduce
- Create a little structure using pink wool and iron ores.
- With WorldEdit (forge) get the struct (.schem)
- Transform online the .schem to .schematic [6layers.zip](https://github.com/cabaletta/baritone/files/5483973/6layers.zip)
- Then build with baritone the scheme (only iron_ores blocks are placed)

## Modified settings
allowInventory : True
rightClickSpeed : 10

## Final checklist
- [x] I know how to properly use check boxes
- [x] I have included the version of Minecraft I'm running, baritone's version and forge mods (if used).
- [x] I have included logs, exceptions and / or steps to reproduce the issue.
- [x] I have not used any OwO's or UwU's in this issue.

Start by reproducing the build with the attached 6layers.zip schematic and inspect latest.log. Trace Baritone's schematic-building handling to compare why iron ore is placed while pink wool is skipped. Done means the structure's supported blocks are all placed as expected.
