After updating Calculator to 3.1.8 and Sonar Core to 3.2.3, my Gargantuan tank appeared empty upon loading my single player world. I could not right click it or otherwise interact with it and had to break and replace it to correct the issue. I thought it may just be a one time issue from updating but after exiting my world and again returning to it, this time with no changes, the tank was again empty and I was again unable to interact with it. Breaking it and replacing it fixes it, but I have to repeat this every time I load my world again. Not sure what the issue is, but it did not appear until updating sonarcore and calculator. This is using forge 12.18.3.2221.

I had encountered this issue myself. However not getting it now. I may have resolved it myself and have just forgotten. Well let me know if you encounter it once I update Flux Networks.

Works great in the new version. Thanks!
