Headspider crushing

[Pestilancer]

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

I'm not sure head spiders really need to be nerfed because they die to a single punch and are incredibly fragile. The reason they survive getting crushed is because they survive gibbing and the crusher gibs.
