Pillagers that are summoned as part of a raid don't drop correct loot. They should only drop crossbows and XP, and arrows but they seem to drop absolutely no crossbows. Instead, they seem to drop random bits of enchanted iron gear such as chest plates, leggings, shovels, and swords. I have also had a few drop enchanted books, this only seems to affect the pillagers and not the other mobs in the raids. I may be in the beta as in the menus it is black like when I was automatically put into beta although there is not the text on the top of the screen showing FPS and stuff.
