Actually I only know it can run but not sure the issues. If you met one please issue at Github.

to update to verB or higher, please follow these steps after you remember your current mc date:

for example:
if before, your date is 2022.2.20
After you updated to Ver B:

reload the script
execute command "/crc.jump()"
(^ this command, in version B, it was "/jtoDate". Now it changed)
send 2022 in chat
send 2 in chat
send 20 in chat
and then click the GO button
Done!
(only able in client.)
