Macodes petola Collapsing

[wwinstanley]

Hi All,

I have had a Macodes petola for a few months now, seemed to be rather healthy. It started off just an inch or two tall with 3 leaves. It has since shot up to maybe 7 inches in height with small new leaves coming through on the upper/new part of the stem.
However it has started to collapse and won't stand on its own, I have it propped against another pot just to keep it upright.
Its growing in a mix of potting soil and sphagnum moss, which is moist but not soaking.

Any ideas on how I can rescue it?

I will get a photo later today
