So I have been running a PLSQL procedure just fine, and compiling with no errors. I made one change to my procedure, and it still compiles fine, but now when I run it, I get this error:

ERROR at line 1:
ORA-04068: existing state of packages has been discarded
ORA-04061: existing state of package body "SCHEMA.XP_COVER_PAGEP" has been invalidated
ORA-04065: not executed, altered or dropped package body "SCHEMA.XP_COVER_PAGEP"
ORA-06508: PL/SQL: could not find program unit being called: "SCHEMA.XP_COVER_PAGEP"
ORA-06512: at "SCHEMA.XP_ST_002180", line 141
ORA-06512: at line 1

Any ideas what this could be? The change I made was so insignificant that I doubt it could have caused this error. Thank you in advance for your help!
