Does my boss have a problem with me?

I had put my name down for secret Santa along with work colleges. It turned out that I had picked my boss out of the hat to buy a present for which I did and it also turned out that my boss was to buy me a present, but while others were passing around presents, my boss did not reciprocate. I'm not sure if I've done something wrong to upset him as I did not get my yearly supervision which I was due over a month ago but neither did another work collogue. Also he has joined in with secret Santa over previous years and reciprocated in buying others presents. I feel like I've done something wrong but it's not obvious or am I not appreciated as an employee or am I just reading too much into this?

Sorry I didn't mention that we all met up for an Xmas meal in a restaurant and this was not planned very well and people got to know who exchanged presents with each other
