Something that is not a problem until it becomes a problem

I am wondering if there is a word or phrase encompassing the concept for something that is not a problem, until it becomes a problem.

Example:

  • Hiring a spouse to work for your company is not a problem, until someone doesn't like them (making it a problem).
  • Politicians taking money from individuals is not a problem, until they take money from the "wrong" people (making it a problem).
  • Copying someone's work is not a problem in and of itself, until the person is affected.

The most relevant concepts that I can think of :

  • Conflicts of interest
  • Plagiarism

If you're talking to the plagiarizer, or the nepotist, for example, here are some ways you can explain potential future difficulties:

  • You are asking for trouble. TFD (crediting Drew in the comment)
  • This could easily blow up in your face.
  • Imagine what this would look like in a headline.

a "potential" or "latent" problem**

  • potential - "capable of being but not yet in existence" - TFD

  • latent - "present or potential but not evident or active" - TFD

Examples in the literature:

  • 1. - "Is the fact that the research is done at two different schools a potential problem with the study?"

  • 2. - "Potential problems related to weightlessness and artificial gravity..."

  • 3. - "Latent problems weren't directly visible to a technician but might occur in the future."

  • 4. - "An example of a potential problem for a couple expecting a baby who already have a two-year old child might be jealousy on the part of the toddler after the baby is born."


A hostage to fortune, perhaps?

To give hostage to fortune - To take an action or make a statement that is risky because it could cause you trouble later.
