Compiling from editor asks for deleted target file

time ago i created a module but then i realized i don’t really need it so i deleted it.
Now everytime i try to compile from the editor (Using the Compile button of course) it says:

Info ERROR: Couldn’t find target rules file for target ‘Alone’ in rules assembly ‘AloneModuleRules, Version=, Culture=neutral, PublicKeyToken=null’.

I searched for the module declaration all around but can’t find any that calls for Alone module (even in uproject file).
Is it cached somewhere? If it is, how can i delete it?
