Surprise from the Venue and invitation problem

So a lot has changed, venue-wise, in the past month. The beautiful river spot where we wanted our ceremony ended up being not available due to people from last year having dibs and "possibly" booking the space again. So we asked our venue if we could have the ceremony on the terrace of the ballroom we booked. We had a meeting at the venue and we found out that there will be construction in the reception venue during our wedding date. The venue was very nice and upgraded us to a larger room at no cost and free use to have our ceremony in their garden space, which is originally $2000. As our budget total is $5000, all of the free things are awesome and we're okay with the changes. The problem comes with our invitations: we sent them in October (early I know, but we were excited and our friends had done the same thing for their wedding the previous year with no issues for them). But now with the changes, our ceremony and reception venue have both changed and the invitation locations are wrong! I desperately want to change them but we don't have any wiggle room in the budget to send out new ones. My fiance said we could just do word of mouth but my heart is also a little crushed: I designed the invitations for at least 4-6 months and I loved them. Now they're like a failed diy project kinda. Any suggestions/words of encouragement?
