We are having the base with crates at the moment. We made a separate crate for medical related stuff and put it on a static table object inside the base.

Some bandages were put into the crate itself, another part was put into the yellow protective case. This protective case was also put into the same crate.

We noticed that bandages which are in the crate became "dirty" (non-disinfected) after some period of time. The ones inside the protective case remain disinfected.

We disinfected the bandages using alcohol tincture and put them back into the crate. Later they became dirty again.

We kept watching and disinfecting bandages for 3 days. It keeps reproducing
