I entered a world where the Royal Winter event kept reoccurring. The events stack and the owner slides on slime to collect them all. Is this a bug?

The server repeatedly spam "Royal Winter Seals for everyone! Be quick you have 30 seconds to collect them!" about 6 times when I entered the world.

Afterwards, it displayed who found the Royal Winter Seals. The problem is, they are not in numerical order. I don't know how to insert images so I will just list down what is seen from my screenshot.

[S] Royal Winter: (Owner) found a Royal Winter Seal! (1/5)
[S] Royal Winter: (Owner) found a Royal Winter Seal! (1/5)
[S] Royal Winter: (Owner) found a Royal Winter Seal! (2/5)
[S] Royal Winter: (Owner) found a Royal Winter Seal! (2/5)

[S] Royal Winter: (Owner) found a Royal Winter Seal! (4/5)
[S] Royal Winter: (Owner) found a Royal Winter Seal! (2/5)

I'm not sure if this is a bug or glitch so I'm making this post to confirm.
