[asdf-devel] recompiling a system when depency system changed

Hello. I have a local project, it's ASDF system specifies :depends-on (#:fiveam ...) The recent quicklisp delivers new version of fiveam. But when my program performed asdf:load-op on that system, the system didn't get recompiled, and old .fasl files are loaded (with error, because they become incompatible). Is it expected behaviour of ASDF or should I dig more and isolate the problem in reproducible test case? Best regards, - Anton
