Although I cant see any documentation regarding call limits, it does appear that it is set at 100, regardless of whether you try and override it in HubL.
{% set plot_database = crm_objects("plot_name","limit=2000&orderBy=plot_no", "site, plot_no") %}
Why it is so low? It most definitely needs to be increased!
I appreciate that I can use HubDB, but if the tools are being promoted, then the cap needs to be sufficently set. 100 is very low for many large companies.
