Hi! I'm trying to get back into Minecraft modding after many years, and after following Cadiboo's tutorial I'm running into a crash whenever I try to test my mod in a world. Here's the crash report: https://pastebin.com/6zyfS9bj
The mod I have right now is very barebones, only two files: https://pastebin.com/j8cNskDW and https://pastebin.com/3QTChgVJ. My programming background is primarily in C# and Javascript, so if this is a simple issue I'm sorry to waste your time, but any help is really appreciated.
