Simple regex using ^ doesn't work in Vintageous but does work in Vim

[99arobe]

The following regex to just remove new lines doesn't work in Vintageous but it does work in Vim.

:%s/^\n//g

However, removing the caret ^ symbol to match the beginning of the line does work (but obviously doesn't match the beginning of the line anymore).

Is there a reason why ^ wouldn't work like this?
