I really wanted to have working garage doors in minecraft survival without the use of redstone since I have flans mod installed and I would like a garage for my vehicles. However, The mod (or malisisCore, both of them could have caused the issue, I am not sure which though) causes tanks in flans mod not being able to shoot shells any further than inside the barrel/gun. I know it is very hard to make different mods compatible with each other but currently I uninstalled the mod because flans mod is the priority for me.
