Demolish Forge

[Purduepilot]

I believe a level 15 forge is all that's needed for all the units, correct me if I'm wrong before the following part pertains. But after I've created an academy, can I demolish my forge back to level 15 without any repercussions, mostly not losing any allocated research points? I just want the extra population if it's no longer necessary to have a level 20 forge and I can still keep all the research

You need a
level 20 forge to build an academy.

By all means build your academy and then reduce the forge back down  that way i can send my ballistas in and destroy your academy, you will have to waste time and resources rebuilding your forge before rebuilding your academy
