BamBam's mother became upset with JYP Entertainment.
She tweeted the following onto her Twitter account two days ago:
JYPE!!! Why you always do different with our family????— Miss Nody (@Gumihojung) July 7, 2018
While she didn't specify exactly what had prompted the tweet, she did say that she missed BamBam and wanted to see him. Combined with other tweets, it seems that she and her family were either not allowed to see BamBam, or that they were only allowed for a very short time.
Some fans are pointing out that while she claimed she hadn't been able to see BamBam or the other members, there exists photo proof that she did indeed see BamBam and Yugyeom. However, most fans are sympathetic toward BamBam's mother and her situation.
Hopefully everything can be sorted out.
