[FIXED BY UNITY. This is not needed at all anymore] Unity sometimes does not reload my scripts when reimporting them. Apparently the .dlls inside /Library/ScriptAssemblies are not always replaced by the generated dlls inside /Temp, so this scripts moves those dlls automatically

UnityScriptReloadFixer.cs

using System;
using System.IO;

class Program {
	static void Main(string[] args) {
		Console.WriteLine("Close this window when you are finished doing cool progress");
		Console.WriteLine("first argument: path to Library folder");
		
		// Path
		string path = new FileInfo(System.Reflection.Assembly.GetEntryAssembly().Location).Directory.FullName;
		if (args.Length == 0) {
			Console.WriteLine("No path parameter. Using default");
			path += "\\Library\\ScriptAssemblies";
		} else {
			path = args[0];
		}
		Console.WriteLine("Using path: " + path);

		if (!Directory.Exists(path)) {
			Console.WriteLine("The path does not exist");
			return;
		}
		
		string tmpPath = Directory.CreateDirectory(new DirectoryInfo(path).Parent.FullName + "\\tmpAssemblies").FullName;
		string TempProjectFolder = new DirectoryInfo(path).Parent.Parent.FullName + "\\Temp";

		
		FileSystemWatcher watcher = new FileSystemWatcher(path);
		while (true) {
			var changed = watcher.WaitForChanged(WatcherChangeTypes.All);
			Console.WriteLine("Change detected: " + changed.ChangeType + "  -  " + changed.Name);
			
			if (changed.ChangeType == WatcherChangeTypes.Created && changed.Name == "BuiltinAssemblies.stamp") {
				Console.WriteLine("Manually moving Assemblies from Temp to Library/ScriptAssemblies");

				foreach (string filePath in Directory.GetFiles(TempProjectFolder)) {
					if (!filePath.Contains(".dll")) continue;
					var scrpAssmPath = path + "\\" + new FileInfo(filePath).Name;
					if (File.Exists(scrpAssmPath)) File.Delete(scrpAssmPath);

					File.Move(filePath, scrpAssmPath);
					Console.WriteLine("Manually moved: " + new FileInfo(filePath).Name);
				}
				Console.WriteLine("Done");
			}
