How to reproduce

1.Load a large schematic file over 400KB in size. The schematic I tested this on was a piece of hilly terrain 4x7 chunks in size and two blocks in thickness with no stone or ore underneath the dirt layer or trees placed on the grass/dirt layer. The terrain was generated in World Paint without any water source blocks present and all of the stone blocks below were later removed in MCedit.
2. Set the schematic file to the desired coordinates with schematica
3. Set the following parameters for Baritone:
buildIgnoreBlocks air
buildSkipBLocks air
buildIgnoreExisting true
allowParkour true
allowParkourPlace true
blockReachDistance 4.5
failureTimeoutMS 2000
chatControl false
4. Run the command .b schematica. After about fifteen minutes, the bot should get stuck attempting to place blocks in the schematic directly above it, but fail to do so. It is worth noting that the bot has the camera aimed towards nadir (directly below) during this behavior making it impossible for the bot to place a block.

To get the modified settings run #modified in game

Final checklist

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