Limit to Quantity of Chillers in EnergyPlus

Using OpenStudio I occasionally come across large data centers with chiller plants containing >10 chillers and each time I face a limit on the number of chillers I can use. OpenStudio allows all chillers to be created and appropriately translates them to the IDF, but it appears EnergyPlus will only operate a max of 10 chillers. Is this a known Eplus issue or is there an underlying issue somewhere else? Is there a fix for this issue besides combining multiple chillers into single component? Thanks.

Note: this has occurred across multiple versions of OpenStudio and Energy Plus.
