Bramble armor can damage beefalo and other friendly creatures

[Pig and beefalo]

This is a very depressing thing. Today, when training beefalo, he was injured three times by his teammate's Bramble armor, which led to the direct reset of the degree of domestication. After about 20 days of training, it was quantified as nothing. After the test, it was found that almost all creatures except the characters would be injured, especially the hired ones. I think this problem should be concerned and fixed.
