Renamed minecart used it on my nether hub rails causing realm to crash and rollback 30 minutes

I renamed a minecart on 1.17.11 back then there were no issues, only after the newest 1.17.30 update when i used the renamed minecart in my realm (used it in the nether) it crashed and reset back 30 minutes causing my 2 shulker box i put prior crashing to disappear
