Price Subscription Error TT Net SDK

One day after successfully starting many market data subscriptions, I start to see the below error in the local TT logs.

2020-11-02 15:05:46.9185721 | 0000014 | Dspch | EXCEP | Exception on Task 'Index must be within the bounds of the List.Parameter name: index' Stack Trace: at System.ThrowHelper.ThrowArgumentOutOfRangeException(ExceptionArgument argument, ExceptionResource resource) at System.Collections.Generic.List`1.Insert(Int32 index, T item) at tt_net_sdk.InstrumentMarketDataBook.applyUpdates(List`1 updates, List`1 existing) at tt_net_sdk.InstrumentMarketDataBook.ApplyUpdate(MarketDataUpdate marketUpdate) at tt_net_sdk.MarketDataBookSubscriptionManager.ApplyUpdate(MarketDataUpdate marketUpdate) at tt_net_sdk.MarketDataSubcriptionManager.HandlePriceUpdate(PriceUpdate prcmsg) at tt_net_sdk.WorkerDispatcher.dispatchThread()

The previous log to the above error is:

I am also using the following setup:
2020-11-01 21:03:11.6815862 | 0000003 | | INFO | SDK Version: 3.0.0.182020-11-01 21:03:11.6815862 | 0000003 | Dspch | INFO | WorkerDispatcher thread starting.2020-11-01 21:03:11.7138336 | 0000003 | TTAPI | INFO | OS Platform: Win32NT Version Major:6 Minor:22020-11-01 21:03:11.7158043 | 0000003 | TTAPI | INFO | Options received - Environment:ProdLive

Does this hint to a problem with my user code or the API?
