Will reloading a table cause recompiles downstream?
Yes, truncating a table with 90k rows will cause a recompile for any queries that touch it.

You could stop that by turning off auto update stats, and in any update-stats jobs or rebuild-index jobs, you exclude this table. However, I'd suggest that you leave it on - after all, the table really could change over time, and you'd want your query plans to update.
