Headspider crushing

[Boxta]

Basically, got attacked by a ling, ended up with ling dying in a welded crate, when they did actually die, not regening, the headspider was outside of the welded crate which doesnt really make much sense at all. Then, the spider went inside of me, i then crushed myself and the spider comes out unharmed.
The spider really shouldn't be able to escape a welded crate and shouldn't also be able to survive the host crushing themselfs
