When I try to color specific words in a power description (in a custom origin), more than the words I try to color are affected. For example, with the description "You spawn in the §1Deep Dark§r, in an §1Ancient City§r.", "Deep Dark" and "Ancient City" are the only words supposed to be colored dark blue, but the words "in an" are also colored dark blue when viewing the origin.
I have noticed that this extra coloring only sometimes happens when I try to color more than one word (with one word, "§r" always works), and that it only colors extra words after and in the same line as colored words that end in "§r". Any words in the next line after "§r" will be the default text color.
