Subject: [PATCH] Catch JsonParseException in entity and block entity names
|
|
|
|
As a result, data that no longer parses correctly will not crash the server
|
|
instead just logging the exception and continuing (and in most cases should
|
|
fix the data)
|
|
|
|
Player data is fixed pretty much immediately but some block data (like
|
|
Shulkers) may need to be changed in order for it to re-save properly
|
|
|
|
No more crashing though.
