EPS files appear visually corrupted when placed into Illustrator

Hi, I'm using the latest update of Illustrator and when I place any EPS file into an Illustrator document, the resulting vector appears corrupted, it has jagged edges, warped shapes etc. If I open the EPS separately, select the vector, copy then paste into my other Illustrator document, it maintains its integrity. As I work with logos all day long (merchandise printing) this is not a productive workflow workaround. I have tried:
- Updating my software (latest version now installed)
- Creating my own logo using latest software, same result
- Saving old logos created on previous software versions into new EPS files using current software
- Saving as alternative file types, including Ai, PDF and SVG. I work with mostly EPS hence my original question, but it is also corrupting the other file types if they are Placed rather than pasted in.

It was always my understanding that Place was best practice, and it seems to no longer be working. I have attached an example. Thanks!
