You sir, are epic.
Thank you very much
It worked very well, some funny stuff like my cable obscuratator turning into a paintbrush and my crystal chargers disappearing but other than that it worked as advertised.
I would suggest you provide instruction on how to use it for the less computer skilled or even better a GUI but hey, it works lol
Here is a mini-instruction guide for you to use if you want
Step 1: Backup your save
Step 2: Backup your save's backup (Seriously back it up)
Step 3: Copy your save folder to the folder with the "IndustrialUpgrade.exe" file
Step 4: Open up a command prompt window (click Start>Run, then type in cmd and press enter)
Step 5: Navigate to the IndustrialUpgrade.exe file
Step 6: Type in the following exactly: IndustrialUpgrade.exe "[Your world name]" NOTE: be sure to put your world name in quotes or it might not work. For example, I typed in (IndustrialUpgrade.exe "Somebody's Lets Play")
If Sucessful it will start going through your world chunk by chunk the bigger your world the longer this will take but eventually it will pause on "Saving..." then return to the command prompt.
Once it does this continue to step 7.
Step 7: Copy your world back to your saves folder NOTE: Make sure to overwrite the old files with the newly modified files.
Step 8: Close all windows and start up minecraft like normal.
Step 9: Go through your world and see what has changed and what has stayed the same.
