Hi,
 
	 
 
	I have been trying to create a custom Slab and have been able to get to the point where my slabs can be placed as half blocks (on both the top and bottom of a block) but the Game crashes when ever i stack them.
 
	 
 
	Any help figuring this out would be appreciated (I am a beginner to modding/Java but i do understand most of the basics) the Original code has come from HarryTechRevs (i was following his youtube tutorials and could find a slab one so i just modified the code he posted on github) https://github.com/HarryTechRevs/Minecraft-Modding-1.12
 
	 
 
	Error from Crash Report
 
	 
 
	My Basic SlabBlock Class
 
	 
 
	MY HalfSlab Class
 
	My double slab class
 
	my blockinit class
 
	 
 
	please let me know if more info is required
 
	 
 
	Many thanks
