I had the same happen with a mounted Gastrochilus japonicus. The spike decided to grow towards the back, until it jammed itself into the cork mount. BUT thanks to advice from someone here, I managed to coax it into a 180° turn.
What you do is take small piece of styrofoam to prop under the spike. At first you can't raise it very high without risking to break it, but as the spike grows and adjusts to the new position you can put taller pieces under the spike.
I absolutely agree!!!!! Yay for styrofoam! just gently lift up a bit at a time. I look forward to seeing it in flower.Keep us posted.
