Topic category: Troubleshooting, bugs, and solutions
Allow me to elaborate on this situation under a very specific scenario.
I am using MCreator 2020.2 (I know it is very old and buggy, but I have to use it to support Minecraft 1.12.2. I have a creative project on this version.)
Three months ago I made a 1.0 version of my mod. It is cool and all was working fine. Then I just finished updating it to v1.1 recently. After I attempted to change the 'Mod Display Name' in the workshop setting this time, the test Minecraft quits immediately after it opens. It is just a NAME CHANGE. I did not change anything else.
And when I changed the name back nothing was fixed. I just don't understand. A name change would cause a catastrophic error for the entire mod?? What should I do to fix it???
I see the stem of the problem is that in the "build" folder it includes multiple duplicated Class and Java files. You see, in there exists one batch of class files named after the original mod name, and another batch of the same duplicate class files but named after the new mod name.
So I try to fix the problem by deleting all files with the original mod name (since I am keeping the new mod name at that moment.) It did not work. When I execute the test environment all of these duplicated class files are regenerated back again. It is impossible to delete them completely.
Please, I spent so long to put up this project. I cannot let it go to waste. Please tell me the solution. Thanks.
