I'm planning on adding a base made of grout to a new outworld. However, last time I did this, my queen died after exploring the grout outworld. Since then I haven't worked with the material. I'm not sure if the two things were connected, but it did happen after the grout got wet, which I've heard can be a problem if the grout hasn't properly cured. The queen started twitching, behaving weird and ended up dead the next day.
So, how exactly do you go about curing a base layer in an outworld properly? You can't exactly soak it, which I have heard some suggest. I could mist it to keep it moist, but I'm not sure if that would be enough. And how long should I wait to be absolutely certain that nothing bad could happen?
And could it quite simply just have been because I used the wrong grout? I think I read Crystals mentioning that some grout was dangerous while some wasn't. I use LIP grout, which is the only stuff I've seen on Danish shelves.
