HLJ "spot production" status?

Who has experience to order models with such status successfully
Does it mean to wait indefinetily when my order will be processed

I dunno. Recently, I ordered a Fujimi Silvia S15 Garage Defend. It's spot production. I image that when you order one of these HLJ just tries to find one as soon as possible whether that be waiting for the company to "spot produce" or just find one somewhere else. Who knows, but I want my Ichi-go!
