Joining Fishing Guild Will Invalidate Cooking

Hello, just looking for info related to if Im joining the fishing guild, will this cancel my guild association with the cooking guild and will I lose my gp?

I know that you can take fishing to 110 while any other craft is 110, but I cant find any info with reference to how the contracts works.

thanks in advance, ^^.

You can only gain GP at one guild at a time but you don't lose GP from switching. While you can level Fishing to 110 alongside another craft, you can't accumulate fishing GP and another crafting GP at the same time.
