1. Update your repo.
2. "exa" is not a good mod id; 3 characters long name can cause conflicts.
3. This method is unnecessary; just do something like:
modBlocks.add(STATIC_BLOCK_HOLDER = new MyBlockThingy("blah"));
4. These loggings at info level are pointless; the player doesn't care what state mods are at, and logging random stuff at info level can clog up the log easily.
